I'd love to be able to create buttons in a Custom Palette. As in buttons with borders, margins, padding etc.
I don't believe this is possible with KM now. I'd like to add it as a feature request and also ask whether any other forum members know of other apps that might allow me to use virtual buttons like this to activate kbm macros.
I'm currently trying BetterTouchTool which has a new Floating Menu in beta but it uses HTML and i've found it to be flakey. I was hoping for something more like a floating touch bar.
BTT's floating menus are an alpha/beta version and are constantly being improved.
The key question is: do you want to click (palette, floating menus) or do you want to press buttons with your fingers (stream deck)? The mouse goes to a button, or the finger goes to a button/icon. These are two completely different concepts.
The thing is that I've found the notch bar on btt to be flakey too. In a way that I don't find something like the Touch Bar simulator or Touché. For me to rely on the buttons they have to work every single time which is something i've not been able to rely on with BTT.
