I like that it can be used to edit shapefiles in Qgis as well which makes life much easier than having 2 separate applications open at once when doing work collaboratively or independently! It's not intuitive enough so far but we're still learning how best use this software together - there are many features of interest here though (including all those mentioned above).
We've been using tatugislive web app since 2016 now where you have access from anywhere via your computer/mobile device without installing any additional plugins etc., just simply add an account through our website admin panel if needed; also great support team behind us too who help out immediately whenever something goes wrong :).
