;;; Commentary:

;; The conda env name and the project name very often are the same so instead of clutter the mode line with the same
;; info just add $ char to projectile mode-line part.
;;
;; If the conda env name and projectile match display : Projectile$[project-name:project-type]
;; else : Projectile$conda-env[project-name:project-type]
;;
;; If the name didn't match exactly you can't modify conda-projectile-name-assoc like
;; '(("some-conda-env-name" . "some-projectile-name"))
