Answer 2

This problem remains relevant. To restore the window size, you can try these shortcuts:

• Ctrl+w _
• Ctrl+w |
• Ctrl+w =

Answer 3

You can set cmdheight to 2 to solve the problem. Add the following line into your .vimrc

set cmdheight=2

Answer 4

This is caused by an incompatibility between NERDTree and Vim 9.0.

You can fix it by applying this hotfix to your local copy of NERDTree.

Some alternatives:

• Add let g:NERDTreeMinimalMenu=1 to your .vimrc to set menu to display in a single line
• Use a version of Vim earlier than the 9.0 release
