Bookmark questions

I'm still switching back and forth between Marvin Classic, Marvin-3, and Hyphen. Comparing all the features in each of these excellent readers can cause an acute brain freeze! :stars:

Have a couple questions about bookmarks in Marvin-3:

- Is there a "Remove all bookmarks" feature in Marvin-3? (Marvin Classic has this option).

- Is there a way to set a "default" color for bookmarks in Marvin-3? I know there is a "Choose a bookmark color" option (red, blue or green), but the choice has to be made each time you create a bookmark. Is there a way to select "blue" and have Marvin-3 use "blue" as the default bookmark color (instead of red)?

Thanks ... :)
