I work at a fairly high resolution and as such when I work with my filters it is not easy to see what a regular expression looks like in the sans serif font I (at least) have as my only option.

If I could specify that I'd prefer to use a font such as Courier instead in my filters that would make a big difference.

Even more helpful would be the ability to make the filter editor (for regular expressions) not only use a non-proportional font but to change the size of it (so, in editor only, use Courier and select a font size). This is something the Lotus Notes designer editor allows and it's really useful!

SEPARATELY, but related to the same area, it would be terrific if I could leave the filter editor open and go back to Mailwasher to look at something else I've done, whether that's looking at my deleted messages log, how I've set something up in my options, or what I have in another filter.

TY!

Both good ideas, I have to edit filters in a text editor so I can see them.
