I'm finding that I'm spending a lot of time going back and removing GUI-generated links (in Zim) - more time doing that, in fact, than I would "manually" entering links to begin with.
What I would like to have (to do, perhaps) with the Zim GUI is what was suggested regarding a checkbox or radio button that will turn the auto-linking associated with CaML case on/off.
I am working mostly with software development documentation and notes - /everything/ is CaML case - I don't mind having to hit ^L to make some text into a link.
