We're using the standard wxColor dialog, so we're limited to what it has
to offer, unless we want to write our own.

That would probably require a custom dialog.

That's probably a bug in the wxGTK color dialog.  I ran into this too
and now mostly use one of the predefined colors.  I don't have the time
at the moment to investigate this further.  There doesn't seem to be a
wx bug report about it yet.

That shouldn't be too hard to implement.  The documentation at least
suggests taht there's a way to get at the data.

That would probably require a custom dialog, too.

It's resizable for me.  However, you can only make it larger and it
really is quite tall (on my system more than 700 pixels with the custom
range).  The dialog should be reworked a bit.  May it should be a
notebook with one tab for the classes and one for the color scheme.
