@thierna It's hard to come up with a complete list quickly because there are simply too many annoyances... Let's see just a few main things:
- UI is wasted. I don't need a complete 3rd column occupied by what should be a collapsible menu. (MastoDeck solves this.)
- I need a column of what I have tooted or boosted. (MastoDeck again solves this).
- I need the ability to clear any column (not just the Notifications) - it's annoying to have to remember what was the last thing you've read and hunt for it.
- No clear indication of how many times a toot has been liked or boosted - only how many replies to it there are (which I don't need) and even that number is often wrong.
- No "quote-tooting" (that's a Mastodon deficiency; not just a UI problem). Yeah, I can post a link to the toot but it's not the same thing and is harder to read.
- No easy way to add people to a list. It should be doable from the menu of their toot or at least from their profile.
- No clear indication of who has boosted a toot - only their avatar as a reduced-size picture, which is often difficult to recognize (MastoDeck solves this).
And many, many other things which I can't recall off the top of my head. Basically, I feel constantly annoyed when using Mastodon while my experience with the old TweetDeck was simply pleasant. (The new one sucks big time and it's only for paid members anyway.)
