Pretty self-explanatory. The title is the same as your blog title.
There's quite a few here, but playing around with them will show you what you do. If you have more than 6 sidebar links, then the colours will just cycle over again.
Content & Post Colour Options:
Again, pretty self-explanatory.
Sidebar Links Format: Offers uppercase, lowercase and so on.
Date Format: Offers to rearrange the order the date is written in.
Year format: As in "14" or "2014"
Post Info Format: Same as the Sidebar Links Format.
For people who get anxiety attacks or even have literal anxiety disorders like me and are like THERE ARE TOO MANY COLOURS TO CHOOSE FROM I'M FREAKING OUT PICK FOR ME this picks for you. If you don't pick one of these options, then you keep your custom colours.
Pretty self-explanatory. The only one I should explain is "Map Standard Colours". This is off by default, but if you're a true Trekkie and want to keep to the standard LCARS colour pallet, then I suggest turning this on while customising because it'll give you the hexcode for every colour available. Just be sure to turn it off once you're done customising.
This is simply so you can rename the links on your sidebar. I thought it would be cool to turn your askbox into a communicator unit or whatever you feel fits.
