A bug I noticed - the backspace in the file creation menu does not work! Bad news for indecisive old me.
Ah! That is a bug and I see exactly what went wrong! I will have it fixed in the next update! Thank you for bringing it to my attention!
The bug has been fixed! Thank you for bringing it to my attention -- it was actually also causing issues with using some letters in file name so overall a very helpful bug to have found!
