Script Exchange

Got tired of having to put a space at the beginning of ever line for code so here's a bookmarklet to do it for you....
http://jsbin.com/ovazew/2
...go to that page and drag the link on it to your bookmarks bar or where ever.
Select the text to indent, then click on the bookmark. Make sure on the first line you select from the very beginning of the line.

Only tested in Chrome on Windows.

If you feel like editing the code for it, then click the edit button on the right and the code for the bookmarklet is in the JS tab, there's code in the html tab to do the conversion. Just click Run JS on the right to create the link. The links title is in the html near the top. And dont remove the //noprotect on the first line, thats a JsBin thing.

Congrats on the new section, it looks great!
You never want a dead looking part of a forum and you've fleshed it out and organised it lovely.
Good stuff!

Oh and thanks for doing mine 😊

Notes: In the code

Scope: Generates a somewhat random alpha map in the largest area of 2^n+1 x 2^n+1 that can fit in the image. For example: 9x9, 17x17, 33x33, 65x65, etc.
