I've been reading up on the Toodledo API 2.0 documentation (specifically the Tasks API, http://api.toodledo.com/2/tasks/index.php) and I can't see any mention of ways to filter results by a "non-standard" field (that is, everything excluding the modbefore, modafter, comp, id, start, and num parameters).
Obviously, tasks can be filtered on the aforementioned, however it seems quite wasteful of bandwidth and processing power on both ends to simply lump everything from one end to the other...
If, for example, I wanted to retrieve all tickets that belonged to folder with the id of 123456, is there a query parameter that I can use to do so? (eg: tasks/get.php?key=xxxx;folder=123456).
Not overly fussed if it's not possible, but if it's available then all the better. :)
