@SchrodingersGat the two issues on top will need addressing before we release the next stable or be mentioned as breaking

Am I the only one who thinks that now the report/label templates in the admin center are a bit confusing if the different models types are all in one table and there is no easy way (one click) to only see templates for specific types? Maybe we could add quick filter buttons to the table actions to quickly add filters, something like this?

I really don’t see the problem, the filters are right there just as with any other inventree table

[wolflu05]

Filtering templates by model type, (which is a really essential filter for me, I always do before doing anything in that table) requires 7 clicks (like 10s) each time I use the table. But if you don't think that's important too, then it's just a personal problem, and I need to deal with it.

@wolflu05 we can (and I plan to) extend the table filtering options to allow you to click on a column heading and filter directly there.

I think #7351 should be added to the task list collection in this issue too.
