Datasets: combo for folder selection

[ajdapretnar]

What's your use case?

Datasets can show many different dataset types, such as corpora, educational data, timeseries, etc. Currently, these are not nicely presented in the widget or they are accessible elsewhere (in other widgets).

What's your proposed solution?

Implement a combo box that would enable folder selection. Folders would be stored in http://datasets.biolab.si/ and shown in the combo. Each folder would contain specific data. If folder data require a specific add-on which is not installed, a warning appears. Settings for the combo a schema-only.

Are there any alternative solutions?
Have many different Datasets widgets.
