Hello PERCE-Neige,

thank you for your feedback!

It is possible to exclude tabs to load from a given profile by clicking the gear icon on the extension menu and then clicking on the number next to its title. Though there seems to be a bug so currently everything is loaded regardless. I will fix this in the next update.

You can rename the profile by clicking the gear icon on the extension menu and then clicking on the current profile title to change it.

Can you specify what you mean by "to make anything with containers from the extension menu"?

If you have further questions or feature requests, please feel free to comment below.
