I like to reply immediately when other people tag or mention me so it would be nice to get notifications for those features. I manage 10 accounts so with the current version of Later, I have to click on each account and then click mentions to see if there are any new ones; and then the same for tags. I don't have time to check these multiple times a day. Even better would be if it were incorporated into the mobile app so that I could be notified on my phone!
