Limit of app developping

Hello,

Just to be sure, there is no kind of app developable to do either:
1.Toybox::Communications in the foreground with the capability of parsing things like speed/power/...? (because deletetemporalevent seems no to work in my app)
2.Parsing json/xml which is stored locally (and manually put on the device via a computer)?

If not, will Garmin plane to improve that?


Thanks in advance
