It would be great to have permalinks for data selections. To give an example: I select all countries, 10 indicators and the past 10 years and then download the data. At a later point I notice that I want to dismiss some of the selected indicators and instead add others. Right now I have to start over making my selections, if I closed the browser or tab. With a permalink I could go back to a previously selected state and make the necessary changes. Apart from that your plans sound great, especially the full text search.
