There doesn’t seem to be a way of clearing a whole lot of history, unless it is all of it, indiscriminately.
Currently, as I see it, you can search your history, and it brings up a list with select boxes. It seems that you can select those boxes one by one. However, the select concept is hampered by the fact that there is no “un/select all” box as one would think, and there no command such as “Delete Selected” exists. I thought that feature was in Chromium, but appears not to be here, unless I’m missing some other setting?
Also, it might be good to be able to white/black list sites that you want/don’t want history recorded.
When browsing my history I see reams of hits for sites like facebook, twitter, etc. I don’t really care about them, so I would like them not recorded. However, browsing history to find that journal article I may have looked up a few days/weeks/months ago in that mess is really hard.
