[Geany-Users] new plugin for automatic alignment

[Lex Trotman]

Hi,

As a general comment, Thomas is right, catching every notify and
re-styling all the text is going to be too expensive.

For example Asciidoc is 6000+ lines of Python, I would suspect that is
too long to use this approach.

You should detect the char added notify and just do the line that the
character is added to, and maybe only when = or end of line is typed?
Don't even look at the previous or next lines.

Cheers
Lex
