Feature request API: add "sequence_nr"

just an example of a API request:
{
“type”:“Feature”,
“properties”:{
“ca”:57.3876375097978,
“camera_make”:“LG Electronics”,
“camera_model”:“LG-R105”,
“captured_at”:“2019-04-15T18:51:06.780Z”,
“key”:“y_ERs99d31OTFBa1rPqaFw”,
“pano”:true,
“sequence_key”:“AfQIHifCXQTB-rz04lX6Qw”,
“user_key”:“XrmaDxUn1aNUHSDJxJLo3g”,
“username”:“eesger”}
,
“geometry”:{
“type”:“Point”,
“coordinates”:[6.0354478,
52.9458689]}
}

I would so very much appreciate the field:

“sequence_nr”:“3”,
That way I could know the order of the keys in a sequence.

I now do a “closeto=A,B&radius=200”

And with that little extra bit of info would save me an extra sequence API-call (sasuming that the result is in order, or otherwise I could order on date/time)

Or is it no problem that I do “more” API calls? (I like to reduce that to a minimum…)

I’ll start programming with an extra API call.

Small question, when working with JavaScript I now have the API clientID in the source… don’t see an other way… is that a problem?
