Features:
it is innovative but not that efficent
Good
Not bad but alternatively
Pretty amazing that it works in the browser. This looks like you're running a VM locally. Will come in handy for an occasional project.
Excellent it is there, but a pity the GRASS plugin is missing. Most used by me, since it contains so many analytic tools..
Good, very good!
Very nice! But not very useful without coud storage media. You need storage to save your progress, to create a layer (point/line/polygon). Responsiveness is also an issue. Nevertheless this is a great experiment!
