It would be very useful to have an in-app purchase for language refs or api docs of many kinds. It could be an option in the files sidebar, so that one could access the language reference and leave it open in the sidebar while one codes so its very easy reference. You could offer it as an in-app purchase for each language and let people get the languages they want. I would definitely buy 5-6 of them almost immediately. Only points would be to make sure they are quite thorough, as in not incomplete. I've bought many other language ref apps and they are often woefully incomplete, not mildly, like the css pro language ref app doesn't have all of CSS3 in it, missing gradients, animation, etc., etc.,  The jquery one doesn't have the templating library, the PHP one doesn't have msqli. These are all very common, so its not like its real obscure things missing. But if it was done well, this could be a very good add to an already great app. I'd buy several. 

Just some way so seeing images

Add support for EC2 SFTP (it uses a pem file as a private key) 

I'm mostly using C at school, but would like to know the conventions for Java and Python as well.  

It would be great to have filters in the symbol window
Filtering either call or definition
Or even better to be able to filter out some strings

the search functionality is great.

another tweak would be awesome. an search result highlighting like metalscroll does. its optimized as variable highlighting. with that plugin for visual studio you just double click on a variable, the plugin triggers an in-file search for that variable and highlights all the search results with a specified color. without an seperate window/widget shown.

so its very easy to track a variable in the code.

you can find the free plugin for visual studio 2008 here

MQL4 is the language used in Metatrader.4. Would be nice to have this support for the portability this app provides.

It is similar to dropbox but selfhostet. www.owncloud.org
