Sorry, I can resend them again, just tell me. (I don't want to spam
the mailing list too much - I have already caused a nasty email storm
on your list).

OK, here's a screenshot:

(Notice the green and yellow lines.) When you load the document, there
are no lines. The first time you modify a line, a yellow stripe
appears next to it. If you save it, it becomes green. So the
screenshot can be interpreted as:

* lines 61-64 have been modified since document loading, but these are
saved on the disk
* lines 65-69 have been modified but have not yet been saved (have
been modified after the last save)
* the remaining lines haven't been edited at all

I find it pretty useful for navigation in source code because you can
quickly visually see the places you have been working on.

It has been introduced by Neil as an experimental feature for
scintilla two years ago:

I had a discussion with Neil whether this couldn't be merged to
mainline scintilla, but he finds the current implementation "not good
enough":

Despite its (in practice not visible) limitations, I find it so much
useful that I decided to port it from codeblocks (which contains
probably the most up-to-date version). I understand that it probably
won't get merged to geany, but some people might find it useful too.

Regards,

Jiri
