* Buttons/links:

  "Look up on LifeWiki"
  "Analyze in Oscillizer"
  "Look up on Niemiec's DB" <-- lifesrch; if doable, since lifesrch uses javascript

* Textfield with image link, e.g. https://catagolue.appspot.com/pic/xp46_330279cx1aad3y833zx4e93x855bc/b3s23/pic.svg

* Sample soup overlay: add a "close" button, add "previous/next soup" functionality?

* Make sample soup overlay drag/droppable? See http://www.webreference.com/programming/javascript/mk/column2/index.html

* Link to haul in sample soup overlay? This basically just needs an MD5 function. Javascript lacks this, but it'd be possible to use e.g. http://pajhome.org.uk/crypt/md5/md5.html .

* "Select All" link for RLE viewer, like on the forums. Dto. for the sample soup overlay.

* Breadcrumbs on census and prefix pages.

* (???) Comment preview - would be neat, but would require parsing and formatting markdown, including embedded RLE.
