Enhancement request: session window tiling

[rmatte]

It would be nice to be able to group multiple terminal sessions under a single tab and have them automatically tiled. As part of this it would also be nice to then have an option to control all of the sessions in a grouped tab simultaneously (which could be toggled on and off) to be able to perform the same actions across all of the sessions if necessary (often the case). It would also be great to be able to manually set the title of each grouped tab.

In terms of the mechanism for grouping them, you'd either need to allow tabs to be dragged together to combine them in to the initial grouping and then allow more tabs to be dragged in or out of that grouping or you'd need to come up with some other method of doing this in the UI. This is a pretty important feature to have when working with large numbers of servers. I often find myself needing to do this sort of thing. Since IAP is a proprietary setup the only option google cloud users really have other than the web console is this app, so it would be great for this app to get some modern style terminal client features such as this.

I love what you're doing with this app so far but I'd really like to see google get more devs involved in fleshing this project out and making it a mainstream thing for google cloud. Sysadmins using google cloud with iap really need a full featured desktop client app such as this to make work more efficient. Trying to use the gcloud command line toolset for iap access with a different terminal client is a pain to manage from a connection profile standpoint and also less secure in some ways as well.
