[Feat] Allow to shrink Data Catalog pane in the Single-window GUI #2210
Description
Currently, there is a limit to shrink the Data Catalog pane in the Single-window GUI (the limit is given by the Data Catalog width, see #2207 (comment)). Would it be possible to allow to shrink it further? I try to exemplify the desired solution in the screenshot below. Being able to shrink data catalog further than the current limit would allow to maximize space for map display.
