The submenu under "Desktop Customizer" have some very long submenu names, like "Applications (Manual)". It would be nice to shorten these names slightly if possible to avoid getting a too wide side menu in web admin now that we use a bigger font there.
One suggestion is by removing the parenthesis so it instead is called e.g. "Manual Applications".
Note that this issue is only really regarding the submenu for TLDC, and the overfilling cause the menu to be wider than usual when visiting "Desktop Customizer" or pages in its submenu. For other pages, the menu width is kept constant.
This issue is almost entirely gone after we reduced the font size of the menu. The only items that currently are too large are specifically the "Applications" entries under the TLDC section, and only when they are selected as the active pages.
