I want to digitize many identical features (same attributes). They will have different location. Type: points and lines. Is it possible to have presets? Like to select: "traffic calming" and then all the attributes of those presets apply, without me having to manually state which attributes that feature has.
No - not as of version 2.16. It's something that myself and a few of the other core developers would love to add but would need someone to step up and sponsor this work.
In versions >= 2.18 you can however set default values for fields, so that could potentially get you part-way there.
