I’ve added a mini Object Manager to Salesforce Metadata Navigator

to make getting to object-related setup pages quicker. 

For example, open an object and you can see its page layouts right in the plugin window. Click a page layout to go directly to that specific page layout, instead of clicking through Object Manager to find it. You can also bookmark frequently used objects for quick access later. 

It can save three or four clicks and the time spent waiting and navigating.
