I beg you, if you are a developer of an open source app or program - add screenshots of your app to the README file. When looking for the perfect app, I had to install dozens of them just to see what the user interface looked like and whether it suits me. This will allow users to decide if the app they choose will suit them… Please, don’t think about it, just do it…
When the last big Twitter migration to Mastodon occurred there were a lot new users complaining about things like documentation, bugs, etc. Old users and FLOSS supporters kept pushing the “its open source, write a doc or fill out a bug ticket” and evem included documentation on how to do those tasks.
Most people just continued to complain. /facepalm
We just don’t live in a world where making the changes you want are encouraged. We have been thought to just accept whatever changes happen or at most file a suggestion that almost noone will listen to. Obviously open source is different but it’s still such a tiny minority compared to how the rest of the world functions
