LO Impress: text field (and other main fields of different layout) needs reset function for size and position

[Karl-Philipp Richter]

Hi together,
it is not clear how to reset size and position of the text field (or any 
other layout (table, video, etc.) main field) in LO Impress. If it is 
possible (and I didn't find it quick enough (as you might expect from an 
intuitive program)) there ought to be a "reset" or "default" button in 
the size and position dialog.
