Improve experience on Dev Statistics: add show/hide per issue type

[Mariusthvdb]

As it is, there is a huge list of entities which one can order by clicking any of the column headers. Currently we can 'group' these per Issue.
This lists ALL entities per ordered per issue.
I have 3 Issues that I consider not to be an issue (I have explicitly managed my includes entities in recorder), and would love to fold under a dedicated selection:

No issue
This entity is no longer being recorded (with a fix issue button)
This entity is excluded for being recorded (with a fix issue button)

But because this list is endless, it is very easy to not spot a true issue, eg:

There is no state available for this entity

please consider allowing a fold in/out or show/hide option per issue type.
witra many hundreds of non-issue entities considered not to be an issue, that would help immensely.

thanks.
