[Dashboard] Units for inputs

[ax3l]

We often, but not yet consequently, end the doc strings of arguments in the unit this argument sets xyz [m].

If we do this consequently, we can parse this [...] ending to show the expected unit in input elements.

Could be used as labels or in tooltips #722

"We often, but not yet consequently"

@ax3l Is this still the case? Is there still to-do work on the documentation side for this?
