Nokia Betalabs

I can't find any difference to the stable version.

What should be make better:
- the check for newer version of a installed app should be optimized. currently not all apps with a newer version will be showed
- a option to remove apps from my download-history
- a option to remove apps from the upgrade-list
- better search-options like exclude-option, inclusive ranking, if the app new, updated or for free
- the recommended view should be optimized, currently they show me apps after that i install the apps (not before), that's not really helpfully
