 ;; TODO (there are more scattered around this file):
-;; - Fuzzy incremental tags/symbol search (Sublime's C-S-r or via Goto Anything # prefix)
-;; - Global code completion is too slow with 23Mb tags file
 ;; - TAGS has to be set up per-project; doesn't allow cross-repository finding afaik
 ;; - Would be nice to have buffers and files merged like Sublime's C-p (but not essential)
 ;; - Buffer reverting automatically instantly if no changes, otherwise prompt the file has
 ;;    been changed underneath and ask to reload or save over
 ;; - Tab key behavior confuses me especially in plaintext files
 ;; - Get back and forward working (currently only back is working; back-button didn't work well)
-;; - Clang-format buffer if nothing marked
 ;; - Compilation-* commands for jumping between errors
+;; - Build system selection via Ido custom list (like Sublime's C-S-b)
+;; - Make tags refresh also cause "macoy-tag-names" to refresh (used for code completion)
+;; - C-S-d fuzzy find symbols often doesn't pick the right definition for forward-declared structs
+;;       It should prompt if there are multiple options
