@lblb Whoa, thanks so much for responding, and so quickly. I toyed around with all the settings and the transparency is functioning as you described intermittently. I think that I tweaked too many settings, including customizing the button sizes to values not available on the UI selector like 6x6. I was really going for a specific layout and then intended to resize the entire thing to be very small in the corner. I also edited the main transparency and the mouse-away transparency options. So, everything together makes the actual click-through transparency function only 10% of the time and I can't reliably reproduce it to isolate it. That's OK. I'm just going with very high transparency of 5 when mouse is away and 15 when mouse is on so that it doesn't get in the way of the full screen video I'm trying to use. [Sorry for the rant] My use case is that I have a video app, www.voracious.app, that is used for learning languages and it has 8 keyboard hotkeys. I wanted access to these 8 hotkey while the video is in full screen. The normal onscreen keyboard covers way too much of the screen. And Toolbar Creator does an amazing job of letting me get just those 8 keys. I did find another paid option in Hot Virtual Keyboard that is more customizable and aesthetically more pleasing, including good transparency options, but it cost $30 for a single license. Your app here is way more than enough for my meager needs and I'm fortunate to have found it. Again . . 6 year later. Wow! Thank you for all that you've done!
