Fix the "Restore" AI Window Size when opening an AI file from File Explorer
What we want is simple, make it so that opening an AI file from File Explorer does not change if AI is in windowed mode, or fullscreen mode.
This has been an issue for years that disrupts the workflow of users on a regular basis. Here is an old forum thread going back as far as June 2012 further detailing this ongoing issue: https://forums.adobe.com/thread/1026020
When opening an AI file from File Explorer, Illustrator automatically Restores down to a window from Maximized mode. While the work-around, (of extending edges of Illustrator's window from edge-to-edge of the desired monitor), minimizes the impact of being reduced to windowed mode, many other users, including myself, still find ourselves re-Maximizing the window to fullscreen.
Adobe, via Creative Cloud, recently launched the first round of 2019 Edition updates, and it would be greatly appreciated if this pesky and disruptive issue would be resolved at last.
Thanks for your time.

This has been a problem for a decade, it's asinine that anyone is paying what Adobe charges when they refuse to address something this basic.

Issue since CS3. Here we are in 2021 and still not resolved. I'm beginning to wonder if this is worth the cost of the subscription. Please Adobe....I shudder at the thought of using the Reef competitor who shall not be named....don't make me switch!!
Seriously though, AI crashed on me this morning with 4 non-graphically intense files open none of which had been saved. I wasn't worried since auto-backup has been working amazingly lately. And yet, I lost all of those files because when I went to reopen Illustrator, upon trying to restore the files it could not do so because THE WINDOW WAS TOO SMALL TO OPEN THE FILES! Come on...you charge and we pay good money for a good product. Fix it, switch to freeware or get out of the way.
