Hi, with the file browser plugin one can easily filter out files by name patterns (in a new sidebar tab named "Files" in case you don't know that). Unfortunately, the check that prevents elements added to the viewed list (`check_filtered()`) is guarded by a `if (dir)` (literally :): https://github.com/geany/geany/blob/bf5c9eddd8a500577719af7fc7f1c1ffb8044a49... I have not tried it but I don't expect any problems if applied to all elements, i.e. to directories as well. Would you accept a patch that adds this?
