On Mac if Wappler is in full screen we are unable to switch projects, to do this you have to come out of full screen and then the option is available.
Is there anything that can be done?
I spend a lot of time switching between projects.
It is possible.. Like you, I switch projects a lot. I find it much quicker to use keyboard shortcuts: Ctrl+Shift+O (Windows) or Cmd+Shift+O (Mac). In each case, I use the modifier keys on the right side of the keyboard, so only one hand is needed to switch projects.
