Re: Proposal for a new feature: import data wizard

Dear Christian,

   this is very close to what I would like to have. Having a preview of the data structure would be nice as well.

I understand and agree with Rene about the usefulness of ReadFile from the command line, but in some cases, when you need to quickly import a simple stream of data, having this one-click graphical conversion tool could be useful. Anyway this is just my opinion.

As soon as I get a bit of time to spare, I will look at your code and try to implement what I would like to add.

Thanks for helping,

Antonio
