No literate person would write "I'm going to My Garage to get My Toolbox and My Hammer and My Saw and My Nails to work on My Project" because one doesn't capitalise nouns except proper nouns, which aren't used in that example (only exception is academic context, such as Science/Mathematics Department or Class/Course, but not when talking about science/mathematics or classes/courses in non-academic context). However, this ungrammatical style is sadly what most user interfaces do, including XDG-specified! I don't know that's because most copied early versions of Windows and/or similar software on UNIX that had program groups with capitalised names despite being similar to garages & toolboxes and not being academic subjects. It's also wrong in standard/classic menus such as 'File Edit View Help' though as those capital letters get underlined, may improve their readability.
As a user, I edited some my X Window System (X) menus to correct to lowercase (except when majoring in science/mathematics, left that entry as-is). KDE kept changing them back, and XFCE (which I now use) may not even let me correct them. As system administrator (sysadmin) for family personal computers (PCs), I corrected the few user directories/folders we didn't want to delete. Of course, as a computer programmer/scientist since before operating systems (OS) were graphical user interfaces (GUIs) I delete all XDG user directories in my own UNIX/GNU/Linux user accounts. XDG should suggest X software give users option for proper grammar of non- capitalisation of everything, especially system (start) menus and user directories/folders. I know I can edit/fork code on my own PC but have higher-priority programming projects. However, for something that makes a project look illiterate, it shouldn't take a fork rather than proper grammar being standard or at least a shown/mentioned option. A bugs.KDE.org person mistakenly told me it's 'title case', but most aren't names/titles rather than generic (non-title) categories--as in my first paragraph's example--which aren't proper nouns. Only names/titles of specific programs/software (literary works) are proper nouns, but even many programmers (since UNIX days) prefer lowercase their program/command names for easier console/shell/terminal usage. Of course, I'm not asking to suggest lowercase for programs/software, only generic, non-academic categories in menus & user directories, categorised same as garages & toolboxes: not proper nouns so proper grammar doesn't capitalise them.
