When you zoom out (on the Board and on schematic) the screen's font size decreases. It would be good to make the letters (or words) at a height of 5 and less pixels to be displayed as outline rectangle. When you drag a selection with the mouse, it would be cool if all the text is displayed as outline rectangles. This will speed up the process of group travel and navigation through the document.
It is very desirable to add an item in the options to select the number of vertical dots in which the appearance of text will become the outline rectangle. This will allow you to select the optimal mode for older computers and large projects.
