More and more of the original Maemo Fremantle frameworks are in place now, so many applications from Fremantle work quite well already in Maemo Leste.

If you have an application you would like to see ported (ASAP), please feel free to mention it here or better yet, in our wiki, https://leste.maemo.org/Wishlist

Anbox or something similar, for whatsapp and banking apps.

Petittrack:
https://www.qsl.net/n1vtn/petittrack.html
light and useful, not too tough to add in auto-gps grab to this, I think it is QPE so old QT but is nice and lightweight.
I used Petittrack with a ham radio walkie-talkie a portable cross-band yaggi antenna and a Sharp Zaurus linux PDA running this for years to play with ham radio satellites when backpacking in the mountains.
(edit)
Failing that a current project is Gpredict
http://gpredict.oz9aec.net/
but it is not optimized for a small display, I currently have a whole very old Debian install to rarely run this app.
Gpredict though is not as easy to use mobile.
Petittrack has easy doppler off-frequency tuning for LEO sat passes, and has sun/moon as easy aiming references for back when we didn't have a ubiquitous hall-sensor(compass) in our devices; yea, N900 too.
Petittrack was no bloat perfect for it's target device limitations(no GPS, no Hall) easy clear fast-pass satellite tracking and manual doppler tuning calculation for ultra-mobile LEO communications satellite users.

Things I would need to Leste be my daily driver and to jump on it when phone, sms, wifi and 3G data works:

Application manager.

Hotspot. Easy way to share data connection with a computer.

Alarmclock.

Mail with imap support.

Firewall.

ukeyboard for extra characters the easy way. Or is there a working virtual keyboard with extra characters already?

Calendar.

Browser. Dooble could be worth of trying to see how that browser would work. In any case something else too than netsurf is needed to get more sites to work properly.

File manager.

Backup.

Easy way set overclocking. And now after trying swappolube proposed settings, speedpatch and cssu tuner to edit transitions they would be good too. Not sure what are the default settings for Leste but after I used these and overclocked to 950 this device changed to be really really fast. If there would also be an easy way for changing swappartition size and change it to sdcard it would be awesome. And how does Leste relate to cssu thumb?

Cutetube2 or something to watch (and download) youtube vids (unless they work with a browser).

A mediaplayer.

A camera app. BlessN900 for example or are there more users for BetterCamera? And something to edit and change the size etc.

Notes or/and abiword (if LibreOffice writer wont be possible).

Something to read PDF.

Working RSS feed reader.

MSoma radio/Streamtuner. An internet radio channel program anyway and if radio receiver works a radio app.

A map/routing app.

For my needs Picodrive solves need for games and no need for porting native games. Other emulators is also a good hook for new users.

But if there is still a lot work to be done then all that developers need go obviously ahead.

I am a mere end user and thinking from that point of wiev. I think these would be something that would be good though if advertising Leste and to get more users. Like some basic stuff.

Don't panic text instead of Nokia Hands is a must for me. Helps not to panic when I have messed up things.

Notepad: That lightweight Notepad what come with N900, but please add Save As to menu.

Calculator: That what come with N900.

The one of the reasons why I change from N950 to N900:
H-E-N (USB host mode GUI): http://talk.maemo.org/showthread.php?t=65232

fMMS: https://wiki.maemo.org/FMMS

Backup: Have to be compatible with that Backup what come with N900

Maps: Or any other navigation software

Evopedia: http://evopedia.info/

Desktop Command Execution Widget: https://wiki.maemo.org/Desktop_Comma...Widget_scripts

Calendar Widget: That what came with N900

Location Widget: That what came with N900

And these when you have time:
Midnight Commander, pCam, RAW viewer, MyPaint, gFTP, Filebox, Gnumeric, AbiWord, Fennec, Hatari, fMSX, mBarcode, Milkytracker, Pierogi, Tuner, HDR Capture, PDF-reader, Radio.

Did I mention Rockbox already?

It would be great if you guys and girls could add the packages you'd like to the wiki too. That allows me and others to make pages for them, add notes, etc. I took a brief look at rockbox, and determined it'll definitely need some porting. libhal, gst 0.10 for example.

Thing preventing me adding packages to the wiki - is that I don't understand what you ask for. What is this wiki you are speaking of (a thread? a site?), if a site do I need to subscribe before I can add there anything, and do you mean I should find the packages from the repository, save them on my N900 (without installing) and then add them to this wiki somehow - or are you just asking to add the names of these application (does it need to be exact package name with version details) to a same kind of post as this one?

I have been 1 1/2 year quite active here and yet don't understand at all what you ask for. Yet it may be clear to everyone else who reads it. It is quite funny how in on something I can be (or seem I'm in).and yet I am actually all the time being so out of things what people are talking about.

"Add packages to a wiki" can mean many things for me and I don't know the right meaning in this case.

How about starting with a comparison of available browsers, such as the one from archwiki? This is definitely the most important piece of software.

Besides, I definitely need the following software to even consider a switch from Android to Leste:
* a reliable IMAP mail client
* a reliable XMPP client with OMEMO support
XMPP is my principal way of communicating with family and close friends, which was the top reason why I was unable to switch to SailfishOS and sticked to Android.

Furthermore:
* MStarDict
* some offline OpenStreetMap client, similar to OsmAnd (Maemo didn't really have decent offline vector maps)
* some Anki client

These apps constitute 99% of my daily usage.
