The (present) normal pointer mode is not accurate enough to use (especially in a combat), and the relative mode is inconvenient on the map (which feels like playing in the Remote Desktop client). Will there be optimizations?
yes, they’re planned for the future: [feature] new UI for melee attack on touch screens · Issue #983 · vcmi/vcmi · GitHub
Nice. It’s same as I expected.
And I hope that can be added to Windows version and can be manually enabled too, because I have a Surface device
And here’s another problem: Is there a way to “hold the right button” on touchscreen devices, in order to display the detailed information about an object on the map?
yes, via long press (touch and hold). And iOS also supports “visit current object” (Spacebar behavior) with pinch gesture.
