Hello they86, thank you. Interesting suggestions, so lets go through them one by one:

- Ok, I will add access to the options page in the right click menu of the BSP2 icon in the toolba,r for easier / faster access.

- Indeed, now that you say it, I see that the visual mouse pointer shape to distinguish an active part (favicon and text in Advanced mode), from a non active part (blank in advanced mode, or whole line on folders or whole line on bookmarks in Simple mode), is not really consistent across Simple and Advanced modes in search results.
So in 2.0.74, I am improving the behavior as follows: a pointer mouse cursor (little hand) will now only show on active parts to open bookmark (= favicon and text in Advanced mode), while a default mouse cursor will always show on non active parts to locate bookmark item (= blank in advanced mode, or whole line on folders, or whole line on bookmarks in Simple mode).
This should be visually clearer and easier.

- You are correct, an add-on cannot override the Firefox bookmark shortcut. This is Firefox security feature.

- "Shift" alone is not possible, it can only be with "Ctrl" or "Alt" .. See "Shortcut values" in https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/commands

- Ok I will see if I can also add a shortcut to open BSP2 in a tab -> https://github.com/aaFn/Bookmark-search-plus-2/issues/130

Thanks, aaFn.
