Hi,
Since you don't have a separate "wish list" forum (maybe something to think about?), I'll stick this here.
When saving prefs in any of the tools, it would be handy to have access to a drop-down menu showing existing pref files, so you could simply select one if you're making changes to it and you want to replace the old one.
Ideally, the name could be editable, if you want to keep the old version too.
In the current setup, you have to type the name in from scratch even if you're just modifying an existing set of preferences.
