While the idea has some good sides to it, I think it is dangerous. Imagine what happens if you pass kst a datafile with thousands of variables? 
I think we need to fine-tune the behavior a bit. One possibility would be to load only the first x vectors (x being in the area of 30 to 40). But other ideas are welcome.

Another idea that comes to mind is using the -w (like "wizard" switch, as we had in kst 1.x) to open the datafile directly in the wizard. 

In fact, I'm still not completely sure what Syam's use case is. It would be nice to clarify it a bit before spending time developing more stuff. Using the -F switch to load the data vectors from a different file, but using a standard layout is a pretty nice possibility if you always have the same data. If it's not clear to you what this feature is, I can give more explanations.

Syam, could you possibly post two sample fiels (one binary, one ASCII) and more details on your workflow? Things like knowing whether you always look at the same vectors or not, or how many clicks are acceptable when loading new data, whether you always want to look at all vectors and how many there are in your files are all important information. Also, batch use cases would be interesting to mention, if you have some.
