Hi, Aldo! I've been too silent for over a year now, sorry. I've been working hard on PKL[eD] lately though, and it's finally taking a form I'm rather proud of. For my next commit there will be remaps and stuff, similar to your remap loops. I hope we can harmonize our efforts in this field. I still haven't made stuff like sticky modifiers, but I plan to. And the help images are better than ever. Not sure about the stuckness of modifiers now, haven't experienced one in quite a while...? But I have a Refresh hotkey in case that should happen.
Regarding vVv's code, I've kind of left that by the wayside now that I've reached a similar level in the areas I care about. My PKL[eD] is now up to date on AHK versions, Unicode compliant and full of little tweaks.
Tip: Maybe you could make a signature like mine, linking to this Keyboard Layout Files Creator topic? It's such a great topic, fully worthy of sig-ness!
