@TerminalAutism @Burn @digdeeper @djsumdog @lina All GUI toolkits in current year suck, that's the problem.
GTK and Qt are both bloat, GTK2 is nice, but documentation is (deliberately) lacking nowadays, GTK3 and GTK4 are more like "let's turn the desktop into something more phone-like, shall we?", Qt uses C++ instead of C, and all the other toolkits are either lacking features, or rely on either of the 2 big ones, or have barely any documentation, or use some weird language they force you to use with it, or worse of all, it's Java.

Also, observing memory usage, there certainly is a difference between GUI and TUI.
Plus a TUI has the added benefit of not requiring you to switch between a keyboard and mouse all the time.
