add command options for tap gestures similar to key and slash #1662
Description
In current code, the touchstart EventListener in editor_ui.tsx is hard-coded to map two-finger tap to Page Picker and three-finger tap to Command Palette.
I find this undesirable, because on both my iPad and my Android phone, I heavily use multitouch gestures for accessibility zoom features.
In older versions I hacked this by commenting out the touchstart EventListener, but that requires a custom rebuild on every update. I imagine it might be possible to accomplish similar with a Plug, but...
If the built-in command.update() API could be enhanced to add a parameter like "touches = 2" or similar, like the "key" parameter, then the 2/3-finger tap gestures could easily be disabled in CONFIG, or even re-assigned to other commands if desired.
