Of the many Lemmy clients I’ve tried, Thunder is the one I like the best, but the one place I have nits is the creating a comment experience.
After typing the comment you have close you keyboard, to have any hope of the create button being visible (if your comment is really short) and then scroll all the way back up to the top. Isn’t the bottom the obviously better place for this button?
Even worse, if in trying to scroll the screen, you accidentally hit the little horizontal bar at the top, you just lose your comment.
Finally, it seems to always lose my place in the thread and put me back at the top after entering a comment.
It sounds a little extreme but I recommend a self-keylogging app. The OS doesn’t let them read password fields, you can generally exclude entire apps you don’t want logged, and you can set how long the app holds onto your logs. Look for one that doesn’t request internet permissions, of course.
