My clear wheels pop out occasionally, too. Without the plate, they click into place. Even though the plate isn't very thick, it's just thick enough to keep the casters from clicking into place.
I have a Logitech Ultrathin Keyboard Cover. It's about a year old, I've only charged it twice, and it works great. I like that it acts like a cover with the magnetic hinge and "latch".
Only thing I wish I had: a skin to keep the cover from getting scuffed up.
I had a day for me, cleaned the garage and dusted off the Turbo Coupe.
Then I moved to the Shelby,and finished up with the daily driver.
Life is good...
