Allow to inject a GTM container on pages matching a specific rule.

This feature should block any existing container and replace it with yours.

This might be useful when the GTM container isn't yet deployed but you want to develop and do tests, or for complex environments where you can't work with the already present container.

This would be especially useful in regex tables when I want to insert a new rule somewhere in the middle of list. If drag and drop is too much of a hassle, some other solution of rearrangement would help, like buttons "move up" and "move down"

Add a button in the GTM preview pane to leave preview, not just minimize it, so it's not necessary to login to GTM to leave preview

Would be great to be able to access the hamburger menu normally only available once you open the Tag within the overview list. Would enable quick copy/delete/pause/etc from the full list of tags. 

Not sure if this is possible but would be amazing time saver when taking over accounts and making large amounts of edits to clients. 

This would save a little time when needing to go down and Pause\Copy a bunch of Tags (or others).  From a UX perspective, Pause and Copy would likely be the "safest" and I can see the UI with two small buttons much like the Refund Transactions within GA.  Plus, I imagine we would want a confirmation for Deleting an element anyway.

News sorting options work well with the GA custom dimensions but does not work with Floodlight custom variables. It actually just sort the values and not the keys, so it's very risky for data collection if someone does not notice. Here's a gif.

When in GTM, it would be nice not to have to scroll to the top to be able to click on the tags. It would be nice if that left menu was sticky or would follow during the scroll.

I frequently sort by Last Edited column to find the tags, triggers or variable that I created in the near past but it defaults to Sort by Name every time I change the page. It would great if we could keep this persistent once we change it. Thanks.

Dark background for custom HTML tags and custom JavaScript variables because white backgrounds hurt our delicate eyes ;)

When Da Vinci is enabled, I can't use GTM. I get this error "Third party cookies must be enabled for GTM Preview to work"

Of course, browser settings are fine. When I disable Da Vinci, everything works as usual.
