There are a handful of things that would really help this tool work better for my use-case, either as features or options.

1) The GPS device is a battery muncher. When the screen is locked, or the proximity sensor is on for either pocket or phone-call or media playing, the GPS should turn off.

Same with taking calls. Just because I answer a call with a hands-free set doesn't mean I'm not driving any more. I'd hate to miss an exit because I was taking a call and the GPS was off...

GPS can also take a while to connect (I have had it take over 3 minutes), so maybe if this is implemented there should be a timeout (for example, only turn off after the screen has been locked for 5 minutes or something).
I would see this as an optional, default off feature. + ticket 113
It could use a timeout/screen-off timeout or some other rules.
BTW, what about a key combination for toggling the GPS ON/OFF ?

I think I'll stick this to the menu, that comes up after a long press on the map surface...well, when there is one Also, I'am planing to add something like an easily accessible Place/Point menu/feature that would report various kind of information about a given point, which could be the current position, a point from the map, a POI, tracklog start/end, etc. I think i could add a "use this point as current position" there too.

4) Saved POI searches / overlays would be similarly useful.

5) Being able to add POIs right on the map itself would be useful. Long-touch w/context menu or swirly-touch seems to be a way to do this.

Yeah, the current POI support is quite basic But I like the suggestions, all of it should be doable:
  • group or individual POI visibility trigger
  • POI search - search by typing in the list + plaintext search
  • show all POI that are on the currently visible map
  • custom POI overlay layers that combine multiple rules to show a subset of the available POI
  • tags ? + tag cloud
  • POI/group colors & icons ?

The icons with blue background were originally used in Rana, which was targeted on the Neo FreeRunner, that runs 480x640 in portrait, which with 3 columns and 4 rows gives 12 square 160x160 icons
I'am slowly replacing the blue-background icons with no-background ones, (that can be batch-rendered by the generate-icons.sh script in modrana/data/gui_source). These new icons are never stretched, just scaled to fit and their background is drawn by cairo - like this, the background can be easily themed without having a complete set of icons with different background for each theme.
