Faster way to open / close sidebar #110
Description
When writing text we often need more space for the preview.
Thus we would like to open and close the sidebar faster.
Currently this always requires moving the slider to mka eit smaller.
Thus: Find a way to make it vanish and come back a bit faster.
Suggestion Double click into the slider bar?
Moreover: Currently the optical bar between the sidebar and the main area is only for visual pruposes and does not react to user interaction. This should be changed. First to make the sensitiv area for making the sidebar smaller or larger bigger and second this could be a perfect solution for this issue using double click.
