Usually I click on 'All' and refresh the server list the first time I load the list, then I can use the filters without refreshing the server list. But, if then I have a filter selected and I refresh the list, all other entries in the list are removed except for the applied filter, which is refreshed.

What I'd like as an improvement is that when I have already once got a (full) server list either the entire list is refreshed (but the filter remains), or only the filter is refreshed but the rest of the list is not cleared.

Hope that made some kind of sense :-\
