Add .dropboxignore directory to exclude folders without using selective sync

Obviously Dropbox will continue to ignore their customers.

This thread is almost 2 years old,but there's still no clear-cut answer.
So Dropbox, please, give us a straight answer: are you planning or not to implement a way to ignore a list of files based on extension, pattern matching or whatever ?

If you don't know how to do it, you may have a look on Owncloud client (https://doc.owncloud.org/desktop/2.1/navigating.html).
Since you are using Qt too you may just copy/paste their "Ignored Files Editor".
If it's too much of work, consider to open source your client. We will be happy to do it (for free. "Free" as in "You don't have to pay")

If you are not going to do it, tell us and close this thread.

Cheers.
