You can create a workspace that groups these sessions together.

Hi Martin,
I have sessions saved like this:

Folder: {project}-{env}-www01
Entry: user1
Entry: user2
Entry: user3
Folder: {project}-{env}-www02
Entry: user1
Entry: user2
Entry: user3
Folder: {project}-{env}-app01
Entry: user1
Entry: user2
Entry: user3

I know that when I click on folder and then click "login" I can log simultaneously to user1, user2 and user3 from that folder. It would be great if there exist way to log into e.g. user1 from www01, www02 and app01, with ctrl+click or something like that.
Is that function exist, or is it simple to implement that function?

Best regards,
Karol
