About the UI that overwhelms the code editor

[liryu1973]

There are three pressure spaces at the top and bottom of the code editor that normally have no role (see image). The left < button changes position every time it is pressed, which is not good, so I think that if it is moved to another fixed location and the information on the right is integrated into C, B will be released and the pressure will be relieved. This may seem like a trivial matter, but when editing code for a long time, trivial things can add up to a mental burden.
