I use a lot of containers (love this extension!) and have an improvement suggestion. It would be helpful if the entire tab was colored, rather than just the little line at the top. I have a hard time seeing the line and distinguishing between similar colors. For context, I have to log into multiple email and website accounts for work. The tab descriptions are often the same (for example, I'll have 3 or 4 google accounts open and they all say "Gmail" or "Admin console") so I have to click on each to find the right one since the colored line is hard for me to see.
