I am using MacVim with the vim-latex plugin. There is a conceal feature turned on by default that converts LaTeX symbols to unicode in vim itself so the source is easier to read. I think this is supposed to turn off on the active line (under the cursor) but this isn't happening, meaning I can't edit the code in parts. Is there a way to make the conceal feature only apply for inactive lines? Otherwise, how do I turn it off?
