Factor libraries: When deactivating a factor library, that library should become "hidden". I'm looking for a similar functionality as for unit groups where you can filter on active / inactive unit groups. In addition, it would make sense to not being able to create new calculation models with inactive factor libraries. Not sure how to technically solve it, as for old calculations the old emission factors must still be shown. However I imagine that clients will get a lot of factor libraries as the years proceed and it will be a bit annoying to see all of them in the long list (as you should not use the ones that are inactive).

Emission factors: Currently, when deactivating an emission factor, that has no effect. The factor does not show as inactive in the overall library view, and you can still choose it for calculation models. Same resoning as above (factor libraries). It shouldnt be possible to set up new calculation models with inactive factors. If needed, then the user should activate the factor and then set up the calculation model.

Calculation models: It exists a filtering functionality for "active calculation models" but there's no functionality for actually inactivating a calculation model (where do you press "deactivate"?). I think that it is a great idea to be able to deactivate calculation models, for the same reason as above (there could in the end be a lot of old / current calc models in the list).
