Hi Marco, can you post your current code or ideally make a simplified example that is not behaving properly so I can run it over here and test it?

For focus, any of the moi Input controls I think should automatically get focus on a flyout menu when the user starts typing stuff in. One example in the regular UI is the Grid flyout, that pops up from the Grid Snap button on the bottom. If you open that flyout and then start typing numbers, keyboard focus automatically goes to the
first numeric input control on that menu. This does not happen by default with a dialog though unless it is marked as a "command dialog" (which is why it works on the mesh export dialog for example) but currently setting that property on the dilaog is not exposed to script.

I'm not sure that I'll be able to help you with the weird behavior one without actually being able to reproduce it over here.
