Needs a proper support page not an email. Custom markers DONT import (they are in the json file)-please fix! Re-creating 14 markers in every profile is not fun. Can't read urls in history window please take size limit off the pane or wrap them.
Good shortcuts now - Need shortcut or DIRECT context (not 3 click, and not a whole sidebar!) to add note to a highlight

Excellent concept. Highlighter linked to note, with clickable index in separate browser page. Excellent customisation of highlighting and easy intuitive use. Can export all highlighted text from one or selected pages with URLs and dates, to paste into documents.

Enhancements suggested:
1. Notes resizing is limited - cant make small enough
3. notes with callout arrow to the highlight would be great.
4. Clickable marker on the highlight for notes (like the one for bookmark) would be very useful to show where notes are and access minimised notes (instead of 3 clicks through page context menu?).

+looking forward to ability to use on FF pages. :-)
