Touch screen mode: enable pop up of auto hide on target at screen edge
This is an excellent VNC viewer app, the best available for Android. But what this app still lacks, is support for popup at edge of screen. E.g. many apps and OS-es have an option when the mouse pointer hits the left (or right, top or bottom) a menu appears. This works when AVNC is in trackpad mode, but not (a.k.a. very difficult) in Touchscreen mode. Particularly when on the target screen for e.g. Windows the task bar or under macOS the dock has auto-hide. Even some apps (Stellarium) have auto-hide as well.
An idea might be when zooming out the local panel to less than 100% so the displayed target screen is smaller than the Android screen so it contains black edges. In that state clicking above the target screen pops up the top bar (e.g. macOS menu bar if auto-hide on server) as if the mouse arrow is moved to the upper edge, clicking left of it pops up the left bar (e.g. the Ubuntu app bar) and so on. That would be very useful.
BTW, implementing this request 'Feature Request: Lock zoom / disable pinch to zoom #169' would be useful as well.
