Guess what? I got greedy!
I'm trying to write a design document describing how to implement 'modifiers' for InsetExternal. It's quite an education ;-)
Ultimately, the problem really boils down to how do we create an appropriate external template syntax?
After reading the document, I wonder what the \executeIfFound is for. I see what it _does_, but why let latex handle an error condition? Isn't it better to simply give a message through the GUI (Your figure doesn't exist/failed to convert) This is much faster as the error is reported so early that latex don't have to run at all. Do we want to generate a .dvi/.ps/.pdf at all in such a case?
An ability to skip some figures might be handy of course, but shouldn't that be explicit? I.e. the user click some "no output" button in the external inset, (or a global "draft" thing) and then lyx don't produce any latex at all for the inset?
I'm a bit worried about the user who thinks a large document printed fine, only to discover later that the tricky figure on page 67 was silently omitted.
