I know many of you have been longing for a way to filter the apps you've paid for into one convenient list. Neither the web nor the app Play Store currently allow this, despite years of outcry. Things are looking up, however, as I believe Google is finally paying attention.
You see, there is a little-known official channel with current top suggestions for Play Store-related features called Suggest a feature for Google Play. You can suggest your own ideas at the bottom, but it also contains a curated list of current top suggestions you can vote for by clicking Suggest it (I think it's a little ambiguous to have a Suggest it button in a list of existing suggestions - it should probably be called Vote for it).
