I suggest adding a indicator when the title length is longer than accepted by Lemmy.
The way Jerboa does it:
- They make the post button gray and make it inactive.
- They change the color to red.
Inaction:
The max length is determined by the server so instead of hard coding a random number on the client I'm going to change the field to show a character count if the counter exceeds 200, but ultimately defer to the server for errors.
