Add .dropboxignore directory to exclude folders without using selective sync

another +1

With all the posts here about lack of pricing tiers, shared folder quotas, and low margins, it makes no sense for Dropbox to offer such little control over syncing.   I sync A LOT of junk like temp files because it's buried in larger local folders with important content and there is no practical means to filter it out.   I looked at using a 3rd party clients which can connect to Dropbox and exclude by type or name, but they lose block level syncing capability.
