Yesterday, I updated into the beta version, and the most inappropriate thing was to cancel the shortcut key. Actually, I moved him to the upper square of the page, which was not in line with ergonomics. If nothing happened, I had to raise my arm to press Cancel, and it was only suitable for one-handed operation. Second, the issue of version compatibility, after the test version opened the file, it was actually returned to the current official version, and the file was actually incompatible. This is so embarrassing. Third, all the buttons in the beta are very uncomfortable. As soon as you enter, you feel that they are not as simple as before. They are all bold and convenient buttons, which is very depressing. The middle bit directly above is actually a fixed and infrequently used key tone that occupies the operation page. I hope the developer can restore the first and second questions and consider the third question. Thank you.
