so funny. The words on your screen are so long while Chinese characters are extremely short .Maybe the officials will notice that. Interesting.

Just a remark to the first picture. There is splitter in File Manager, but it has range with max width.
And it doesn't have it in File Open dialogs

I dont have first problem, but you can change default font on Droid Sans Fallback and fixit text's bags in depiin menu

There is a splitter for the left sidebar which allowed you adjust the width max to 200px. The splitter is also exist in open file dialog, but the mouse cursor sometimes is not correct. You can still drag to adjust the sidebar size through.

The mouse cursor issue in dde-file-manager is a known issue, we are working on this.

Thank you, but 200px is too small and splitter doesn't work correctly in "open file" or "attach file" dialogs. That's the problem. (The cursor doesn't change)
I think, developers should just remove max-border - let the user set splitter as he wants
