I wanted to change my dark theme, so a week ago, I started with the minimalistic theme and edited it in my spare time:

• I wanted it wider, so I set body width to 700px from 500px
• removed cufon to google web fonts (now using Josefin Sans)
• I often use tags to better give a context to my posts, so I added the tags visualization
• changed color for posts metadata and borders from #BCA474 to #85B5A5
• I removed some borders in header
• aligned all images and videos to the center of the page (they are still 500px wide)
• moved the search form below site description
• titles to the left
• added support to linkedin profile’s url

Next steps? To let users set some variables to customize it in a simple and immediate way (if you use tumblr you know what I mean) and then submit it to tumblr

• clean up css
• set #85B5A5 as a customizable field text
• set also the google font name as a textbox in the admin panel, to change font in seconds
• support other social networks in the menu
