When attempting to edit character sheets its a little infuriating how small some of the boxes are and that they have limits on the size. I've got a 4k screen and 300 pixel in height is tiny for a text box (even in 1080p this isn't exactly large and resolution bigger than this are very common now) Don't think this would be particular hard to do and default 300 pixel size is fine but I don't see why It need limits on the size really, let the user decide how big they want their text box to be when editing. If you find this annoying too, one work around is to open dev tools and inspect the element and directly edit the max height attribute of the text box but yeah shouldn't need to do this
