Collapsible UI sections

[leoyala]

🚀 Feature Request

It would be ideal to have the option to collapse the main controls located on the left side of the UI.
In addition, having the viewer buttons placed inside a dock widget will allow them to be placed either vertically or horizontally on either side of the main UI window.

🔈 Motivation

These controls are needed at the beginning when setting up store folder and file name, but while the recordings are started, most controls are disabled, and therefore not needed.
