@sloth Giving advice over text is a ballache, but I'll try.
1. Open album edit page
2. Open developer tools (for me, it's ctrl+shift+i)
3. ctrl+f and search for "maxlength"
4. Find the line that looks like this (I'm using the album I just fixed as an example):
input type="text" name="album" size="30" value="When You Get There, Tell Me What The Sky Sounds Like" maxlength="40"
5. Change the "40" to a larger number.
6. Edit album title as normal
Note: this won't let you make album titles 5000 characters long or something. There's still a capped amount. But this lets you fit a little more than you usually would be able to.
Also, you can do this when first adding an album to the site. This is actually the best time to do it, as you get even more allowed characters.
