This is what I use, and I had totally forgotten that you could switch layouts. I switched from windows to Linux Mint Cinnamon about 12 years ago, and then to Ubuntu but I didn’t like the gnome menu. Having grown up with windows, that style of menu was what I was most comfortable with, and ArcMenu was there to fill the gap.
Same! I eventually overheated mine and it caused the digitizer to stop working in the middle third of the screen. So disappointing. I traded up to the droid RAZR and many phones since, but I STILL miss the slide out keyboard.
