Actually, since the modern behavior is reasonable by default (the "Limit" field is not required, and defaults to empty, and the panel works properly if "Limit" is left blank), users have to explicitly set a limit to get any unintuitive behavior here. If they do, they still get a "View All Results" hint.

The bucket limit is currently implemented like this:

I'm just going to mark this as "Wontfix", since:

These work now. If they see use, we can build them out in greater detail.

D20377 initially added the warning this task originally suggests, but we weren't really thrilled about it so it eventually landed as some minor cleanup with no actual new warning.

I marked this as resolved in D20384, since that rewrites this interface and solves this particular issue. The new UI is still fairly rough (thus "v1 Major Jank Edition") and has some new replacement problems, but see T13272 for followups.

This might be nice to have some day, but we don't really have open requests for it and I don't have any particular plans to pursue it. The existing set of options seem reasonably sufficient and clear as-is.

Panel type selection should be a modern "clickable" menu.

Currently, Dashboards have a "View" mode, an "Arrange" mode, and a "Manage" mode.

T8033 - I'm not really sure what's left here...

The remaining bugs I want to fix here are:

I'm going to claim this is possibly "resolved" by fixes in T13275/T12871, especially D20359. Once those land, you can put a list of dashboards in the menu and users will default to the first one they can see. The others will be marked as "Restricted Dashboard".

I think this currently lacks compelling motivations and isn't particularly actionable, so I don't plan to pursue it until new use cases arise. (It's also fully modular already.)
