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

Create a multi-purpose, rich UI to diagnose all tags, showing detailed dataLayer values and events - think of it as a next generation WASP tool. Advanced features will include visualization of tags calls hierarchy, compatibility to dataLayer, ability to block or alter requests, data dictionary, etc.

Please comment with suggestions of what you would like to see in a powerful tag debugger.

This will be a subscriber-only feature.

When looking at a GA report that has a time series graph, show control limits, trends, and maybe forecast

Title says it all: it would be interesting to be able to easily do a PDF of all pages in a dashboard.

Allow copying of calculated fields from one data source to another

When I click to turn on the heat map in GA tables, it briefly activates, but then the table sorting happens and the heat mapping goes away.

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. 

It would save some time if I could just click CTLR + S (or CMD + S) and Tag's/Trigger's/Variable's settings would be saved. Now, I have to move my mouse every time to the top right corner of the window.

When looking at some reports the first column of metrics jumps/moves beneath other fields. Still sortable. The metrics are still where they should be.
