[sugestion] Preserve the tabulation level after pressing new line

[Lukasz825700516]

It would be nice to have new lines of commands auto

• indented to the match last indent level
• based on the depth of brackets
• based on the depth of brackets, but add/remove maximum one indent at once

Preferably based on the option in settings, or to disable such behavior (current).

I could try to implement it after investigating more #20
