Description:
Modern office suite aimed for optimal productivity –as it seems to me undoubtedly the case regarding the product Libreoffice– should tend to make an optimal use of the device's available screen surface. 

The present report is illustrated here by focusing on a random case –here the tool Special Characters (no application short-cut available (e.g 'Ctrl + CC'))–.

Steps to Reproduce:
From menu Insert, select Special Character; Plural form seems to me accurate (Opened window's title bar 'Special Characters' just does it that way).

Actual Results:
Attempt to invoke expansion of the tool-window to full screen by action of double-left-clicking title-bar is not implemented.

The surface of Characters' area is presently not adapted for the visualisation of an optimal number of characters, Then –manually– increased window size do not benefit that number. 

Both sections, Recent Characters and Favourite Characters, are currently displayed persistently, which affects as well the  optimization of the screen surface.

Time needed to search for a new character –e.g. LEFTWARDS ARROW OVER RIGHTWARDS ARROW (H: 21C6; D: 8646)– speaks for itself. once selected (is individually displayed on blue background) and Font list is clicked, the right-sided-character section –which displays information related to character– displays irrelevant information while scrolling throug the font list



Those aspects comined do certainly affect negatively productivity.

Expected Results:
A feature associated to each section, Recent Characters and Favourite Characters, aiming to hide/display their contents would be appropriate. 


Reproducible: Always
