Please add a feature Bewertet mit 5 von 5 Sternen

would you please add a feature with name of "Lock Similar Tabs" ?
for example we opened 20 Tabs. 10 tabs from google.com and 10 tabs from yahoo.com.
then we decide to lock just 10 tabs of google and close other tabs.
for now we must click on all google tabs one by one while takes lot of times. but if you develop "Tabloc" with this feature will save us many times and appreciable.
Thank you.
