I've just pushed a pretty cool new feature (at least in my opinion), and it's something I've wanted to do for a while now!
On the blocks overview, instead of the checkbox that used to let you show only transactions you will now see a dropdown selection box on the right side. In that dropdown you can choose any type of transaction that you wish to see, and you can also combine different types. This lets you easily browse through for example all blocks containing an asset creation transaction, or a cover transaction etc. If you are on the "recent" page, ie the first page, you will automatically receive only new blocks containing the chosen transaction types.
To return to the default view of showing all blocks, simply deselect any transaction types in the dropdown.
There might be bugs so let me know if you find any, and although I've done my best to optimize the search operations on the backend they're still a little slow sometimes. I could also use some help with translations for some of the new terms, you can find them on github.
I've also temporarily disabled an api call that was fetching a list of delegate names that might've been the cause of some recent access issues people have been having, I'm gonna rewrite that part tomorrow but until then you won't see the name of the delegate who caused the previous fork and the typeahead in the delegates overview doesn't work.
