Ok here is something fun I've never done before in my wallet. Preferences -> Display -> Third Party transaction URL: http://test.insight.masternode.io:3001/tx/%s

If you put that in there then when you right click on a tx in the transaction's tab you will get a link directly to the explorer. Keep in mind for this to work on mainnet wallet's you'd need to use port 3000 for the explorer link not 3001 and you'd need to drop the test from the link.
