My Lands: Black Gem Hunting

A vast majority of messages are of gov. (blue symbol) type which makes this group ineffective to search through. The first step i suggest is to at least exclude explorer related ones to a separate new type. This would still be the biggest group but also keep the gov. type reasonably full.

Furthermore a selected type may still be subdivided, eg. selecting explorer type and buttons to filter appear: very-important-object (lake, arch., stone...), rank suitable ruins, other ruins, other explore info.
