Hello,
Feature requests via e-mail or GitHub only please;) See also the remark on the main page (https://addons.mozilla.org/en-US/firefox/addon/textmarkerpro/) right under "About this extension".

@folder: The history works with tags (instead of folders). You can add tags to each history entry and filter your entries by tag names; this has the same effect as opening a folder - instead of putting your entries in folder "someFolderName" just add the tag "someFolderName" to those entries.

@local directory /
@ref to Wired-Marker:
I'm not sure I understood what you mean. Please follow the feature-request-procedure mentioned above. E-mail is fine, but opening an issue on GitHub lets other users participate as well.

Best wishes, underflyingbirches
