Quantopian = Wow
...and as if you don't already have a vast todo list with high priority, here's a pitch for an idea:

The little things can matter a whole lot

My list of tiny changes that I think can make huge differences. Imagine if the whole list could be handled in a day maybe. Inviting anyone to add their potentially easy/quick to handle issues if not complex involving the API etc.
(Some of these might only apply to my environment, Windows 7 and Firefox)

1. Make double-click anywhere on a word highlight that word. Currently seems the click has to be nearly centered on a letter for the highlight to take.
   
2. [Edit, done 2014-12] On right click -> 'Select All', do not scroll to the bottom.
   
3. Make user start date and dollars stick as default for new algos. (Of late I almost always change defaults to 01/01/2009 and $5000 for example).
   
4. [Edit, done ~Apr/May 2015] See if you can find a way to make copy/paste from logging window preserve user carriage returns (\n), possibly a simple CSS addition.
   
5. For multi-line comments using pairs of """ or ''', make the highlight color match single-line (those with # at the beginning), currently, for 1/10th of certain males including me that are somewhat red-green colorblind, it appears not so different from normal text.
   
6. Find a red-green colorblind person and ask them to help you pick colors for the custom chart that are easy for us (and still others) to distinguish from each other.
   
7. When the date range slider is used on the custom chart and resuming in debugger, don't reset to full scale.
   
8. Make user list of algos sortable with this easy-to-implement javascript for example.
   
9. Add a button in Community for inserting images (it's possible now, just more steps, requires upload to another server first)
   
10. Move the search input box left about 20 pixels to not cover the upper scroll arrow (cosmetic mainly).
    
11. When doing a search in code (Ctrl-F for 'Find'), start the search from the cursor position.
    
12. After a search thru code, then focusing away from the search input box and click to return to it, automatically highlight the current contents to be able to easily type or paste to replace.
    
13. [skipped to play it safe] :)
    
14. Maybe change the 'Build Algorithm' button to 'Save and Build' since it does an automatic save (glad of that).
    
15. Add a thumbs-up button for backtests in the Community (altho maybe not thumbs-down).
    
16. Add Returns column to paper/live algos at the top of the Algorithms page.
