why Don't add constants where value is not a number? what constants are included that are not numbers? Edit: just a curiosity question, its probably good to have that check there anyway.

removal of ImapFolder config option?

what is that option about?

what is that option about?

that's the question? its the watch folder setting afaik and the new core watches all folders if i understood it correctly, so my question is whether we need to remove the watch folder setting from desktop when using the new core.

i see ;) the options should stay as is for now, might be they get superfluous at some point, but we are not there yet.
