Actually, I think it’s great enough if they are able to group tabs that are opened at the same time in the different windows. All we need to do is to open a new window tab before doing research (which is also what most of Caffein8’s staff are doing) because we want to keep our original tabs intact.

By changing this simple interaction, we are able to track our history properly and group them by the time they are opened together. And with that, we are able to link them together much better.

Just by implementing this system + window management.
