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.
The post UI appears to have the create post button at the top also, and have that same potential to lose your text by accidentally catching that bar when swiping to try to scroll down.
