This has the potential to be an absolute game changer, but it's not consistently working for me. Seems to work at first, and then stop working. I'll try to give more detail. For sxs4's scenes, that have dozens of numerical buttons, it could be fantastic.
I found an issue with a previous version where it was improperly handling the disable and re-enable events, but I put in a fix for that with an update, and it is working for me consistently since then. So, keep an eye out if you're doing any disable/enable or reloading of the plugin or anything like that, as something there may yet be the cause for some scenario where it stops working.
