It would be really useful to have filters in the Log Viewer be either include or exclude. Currently they are only include.
For example, if I want to see logs from all sources except a certain device model, currently I have to create an include filter and check off every other model but the one I want to exclude. Since the filters only show values that are present in the current view, it's impossible to include other models that just haven't logged within the current filter, meaning they could be missed by the include filter.
It would be much easier and more useful to be able to filter on whatever value I want to ignore and toggle it to be an exclude filter (i.e. show anything that does not match).
