I assume you mean the scrollbars on the edit window, those are drawn
by the Scintilla editing widget Geany uses, and AFAICT its API gives
no way of setting that width.

Did you check if the file exists?  Or has been installed to a
different location?

Not sure why this uses a different method to the other help, although
technically the other is better as it uses the native open that will
choose the default browser without having to have the
Preferences->Tools->Browser (default "firefox" as you found) setting
configured.

The 4 th line of the help file should be:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

so it should open as UTF-8, maybe something went wrong in the building?

You can make an issue for that, but probably somebody will have to
contribute the code for it.

Request a feature addition, although I think the timestamp is added by
Glib, so we might not be able to control it.

Not sure what "copy as path" is, but its not something Geany supplies
or uses, presumably its part of the native dialog, so Geany has no
control over it.

There does not appear to be any Geany code, its in Cairo dll.

But if it is a callback while a dialog is in progress that calls Geany
then its potentially a problem, Geany is not reentrant, its expecting
to wait for the dialog reply, not do anything else until thats
complete.

Its possible that happens :-) did you google?
