Thanks Eric.

How would you feel about a feature that did parse all files and store the db
in memory? That way when I do "someSymbol." I get all the tags beloning to
someSymbol in random access time. Is this not what intellisense does? I do
not know if it stores it in memory, but at the minute I cannot see why this
would be a bad idea. The only issue that comes to mind is if something
changes - if I add a member to a class as long as semantic can append to the
database in real-time I think it would be fine...

Cheers.
