Not a biggie but would it be possible to make a double-click on a rule open it for editing? I know it can be selected and then the Edit button clicked. However in similar GUI contexts in general as a shortcut the user is often able to double-click a list item to invoke a default action.
Except that the last C / C++ related code I wrote was at a hobbyist (i.e., incomplete knowledge) level 25 years ago. It was console C, not GUI C++, and I have zero knowledge of GTK. The closest I got was poking a small sharp stick at the Win32 API YEARS ago… And I even gave away my Petzold book. LOL
Actually I’d love to contribute little code snippets to a project but I’m afraid I’d do far more damage than good… especially since I have no idea where to start. I’ve actually browsed various changes you’ve made over the past year or so and it’s usually pretty opaque to my non-OO / procedural-C brain.
