Back button in main browser

I really think that the main browser window needs navigation buttons to return to previously opened documents.  I’ve begun adding wiki-style links to my documents, and will click on them to open up the file or group that i’ve linked too.  But then once I’m there I want to get back and to do that I have to remember the path of the previous document that I linked from.  

Navigation enhancements have been discussed in other threads and were said to be coming in future versions.

Thanks for the suggestion - and such commands will come. Either in v1.8.2 (if such a version will be ever released) or v1.9.
