MajorGeek says: 7-Zip Theme Manager is a nice little utility to customize the appearance of your 7-Zip file archiver with multiple toolbar and filetype themes. Not that there is anything wrong with the standard theme provided by 7-Zip, but some users enjoy the ability to customize as well as the added benefit of larger icons which can provide some welcomed eye relief. With 7-Zip Theme Manager you effectively get the fast speed of 7-Zip coupled with the polished look of PeaZip - which is the best of both worlds.
