Hi,
I notice the items in the symbol list disappear when you're inside a global "string literal" (or #include using quotes, but not <>) that isn't closed yet. Only the symbols below the unclosed quotes disappear.
This is probably not a new thing, just noticeable now that the symbol list is updated in real-time. My guess would be that the parser just refuses to handle the rest of the file in this case, but maybe it should skip to the next line and keep going or something, if this is even possible.
I just thought I'd point it out since I noticed (it's visually distracting). It's not a majour problem or anything.
