Hi robin!
I really like your icon pack and I've been using it for some time now. There are some apps which I don't put on my desktop though I want to because there are no mango icons for them and since you are looking for request, here's my list!

1. Evince - document reader
2. Word to Go - MS Word equivalent
3. Sheet to Go - MS Excel equivalent
4. Qvernote - Evernote client
5. Countdown timer
6. VGBA - gameboy advance emulator
7. Wgames - webOS games manager
8. FBReader - ebook reader
9. MyPaint - drawing app
10. Tweego - Twitter client
11. fMobi - Facebook client
12. Firefox mobile

I'm in no hurry and these are just requests. Thank you for the wonderful icon set!
