Maybe it is time for me to try project-mode out again, then?

Is there an overview on what kind of commands are available in the emacs
28 project-mode?

By this time I have about 6 months of actively using projectile (once I
got the startup issues cleared away and using the cache instead), and
I've quite grown to like it.

I have replaced navigating with switch-to-buffer with the
projectile-find-file file command, and switch between projects with
projectile-switch-open-project command and find a directory with the
projectile-find-dir command (the find file and find dir commands stay
within a project).

So that has mostly replaced my need for .emacs.desktop.
(The only reason I'm still using .emacs.desktop, is to restore the open
windows.  Is it possible to have .emacs.desktop restore windows but not
files?)

Other useful commands:
 - projectile-grep which rgreps inside a project useful
 - projectile-compile-project (very useful for maven projects, where the
   mvn command must be run at the top directory of the project far from
   the file being edited)
 - projectile-find-tag (very useful, once I was able to make CTAGS
   recognize ES6 javascript)

What I'm missing are commands that do the same thing as the project
level commands for project modules, in particular for maven multi-module
projects.

The most important command to get a module command for is the compile
command (because building a single module takes a lot less time than
building the entire reactor build), but module specific search and
navigate commands would also be useful.

Does project-mode have a concept of modules? (the maven concept of
modules is what's in my mind)

Thanks!
