option to manually increase the readable space by adjusting the size of top bar, side bar and bottom bar or closing them when desired.

when i try to zoom out, it is more awkward and the redability isn't good. (as shown in the image )

it will be nice if i can close the side bar when not needed or reduce the top bar size and the content fills up maximum space and improve readability.

post this here please. https://thi.ai/topic/69
