First, thank you for making this very cool editor!
I’m frequently using Lines > Auto Indent to beautify HTML code.
It seems like there is a problem when multiple tags are closed in the same line, if they were not all opened in the same line.
E.g. (not my code! other people or tools write like that):
This is a table cell
The last line () should have the same indentation as the first.
Because of the bug it will be indented in.
By the way, code beautification is very important.
Could you possibly move it directly under “Edit”?
