Today I tried something and got some good results. I started out just trying to improve the support for multiple monitors, which has never looked very good since Windows XP which allowed you to go full screen on multiple monitors. I have a dual monitor setup and it's the best experience on my computer apart from VR. It has the advantage of allowing me to type. The annoying thing was that I had to manually pull the window to the biggest size and then the title bar and borders were always visible.
Today's improved support so far (in my version) is a text command /window max which adjusts the LFS window to be the size of the entire extended desktop, with no border (style WS_VISIBLE).
I'm really pleased with the result. It works in single monitor mode as well. But there is a little strange behaviour with the task bar so I would like to ask here because many of you have experience with other sims and games.
What happens is when I go to the new full sized borderless window, the task bar may be visible. I can click on another program in the task bar and then minimise it - then the task bar vanishes. I can still use ALT+TAB to get to any other program. It's very nice that the bar vanishes but it can also be useful to see it. Sometimes the appearing or disappearing seems a bit unpredictable. Sometimes visible, sometimes not, sometimes visible for a second then disappearing. Is this normal behaviour for programs that use a borderless window?
Another point to consider: In these days of monitors which have a native resolution, I'm not sure we need SHIFT+F9/F10/F11/F12 to be assignable to four different screen resolutions. That seems like a relic from the CRT days. I am thinking that maybe SHIFT+F9 and SHIFT+F10 could be assignable as they are now, but SHIFT+F11 could go to full screen at native resolution (desktop resolution) and SHIFT+F12 could go to this new borderless window mode on the extended desktop.
