Adapt GeoForm for Number Keyboard on Mobile

[MantasButrimavičius1]

It's a pity that GeoForm cannot adapt number keyboard on mobile. If there is a field that can only accept numbers (e. g. float format), it opens standard keyboard:

GeoForm should open only number keyboard as Collector does for number values:

Also, it would be nice if GeoForm could recognize emails. In other words, then I try to enter an email in a GeoForm, the first letter should be lower case (usually it autocorrects itself to upper case). Moreover, the keyboard could also change to include @ symbol and .com ending.
