During process of developing an App, Data Model, Importing Data etc... it is necessary to load manually Data into the App.
In one hand you have to take a look how it looks in the App (Analyse tab) and then swith to the Data Model tab, presh Data Load and go again back to see if everything works fine.
Would be happy if the Data Load Button would be more prominent so you can access it fast and without clicking too much tabs.
I did asked the product manager to review both ideas prior to marking this one a duplicate. The idea is not exactly the same, but the intent quite the same...an easy & fast way to reload data. Adding your support to the other idea may help bring a solution quicker than keeping the ideas separate.
