Is there a (modern...ish) software that is being actively used and developed in Pascal?
Not Pascal Pascal, but a spinoff: AL for Business Central (Microsoft's ERP system). It is a very old system, but Microsoft heavily develops it (every year new language and std lib features, first class VS Code integration). Userbase is pretty big (and seems like it is growing).
Total Commander is an orthodox (2 pane) file manager written in Object Pascal.
