As far as I understand B4XPages is the modern sugested way to work with multiplaform applications. Under Android pages are on a stack and this is ok, but under a desktop Application sometimes this is annoying, and you only want one page at all at the same time, or you want the page to be opened modal. How is the way to go? I noticed there is a ShowPageAndRemovePreviousPages. It's this the way to go for App navigation? What about modal forms?
