Some of the annotations in the `project-file` type commands where you first select a project and then a file are a bit shaky, due to marginalia not yet providing very good support for these types of project commands. For some commands (e.g. `doom/find-file-in-other-project`) both the project list and file list get file annotations, but for others such as `projectile-switch-project`, they don't really get annotations.

Note that there is an interesting alternative to the which-key indicator, the recently introduced verbose indicator (it's what's used by default). it looks like this:  this is more useful than `which-key` information-wise, but breaks with doom using which key everywhere else, and this information can also be reached by pressing `C-h` to start a vertico filtering session.
