I don't know that they are "catch up updates". Some of them are, some of them aren't.
Since we're on the subject of updates, what would everyone's most wished for features be?
I'll start:
OS
- VPN support
- improve stability, make sure files do not go missing into the dreaded "other", other bug fixing
- alternative unlock methods, pin just doesn't cut it. Pay Google for the screen pattern or come up with your own thing, just give us something better
- make live tiles more interactive (ie, let me flick on/off wifi without being redirected to the settings)
- custom live tile update timings ("update every ... minutes")
- improved/integrated search. Take a cue from W8 and make the search similar, so you're able to search the web, files, other apps (including 3rd party apps)
- improved speech control, there's a lot that can and should be done here
- IE interface improvements, more customisation options
- 3rd party browser support
- release keyboard API's, I want 3rd party keyboards (I miss Swype)
- ability to keep lock screen on when charging/playing music (it's a pain in the arse to go to the next song while driving)
- yes, please do include separate volume controls
Music
- improved sync agent. Integrate it with the music app on W8. Improve it a lot. And then improve it quite a bit more. Or preferably, go back to Zune.
- wireless syncing
- include podcast management. Things are a shambles on that side.
- add videos to the store
- easier music file management on the phone
- better integration of the store
- better playlist management
