as "multi touch" touchpads are more widely used these days, AmigaOS should get a (configurable) "sticky" right mouse button. I missed this function today, as I tried a Logitech K400 keyboard with touchpad. The right mouse button is done with a two-finger tip on the touchpad and it works so far. A drawback is, that this is a "single shot" function. A menu will be closed instantly right after opening, if its not "sticky" by nature (e.g. the Icon context menu). With a sticky right mouse button, all that is needed to "release" the button would be a second two-finger tip on the touchpad.
It could be used even for application and game software, as it is just some training that is needed to make fast right mouse button clicks with a touchpad

I dont know how hard or easy this is to implement, but it would be nice to have such a function.
