comment Split by attribute automatically on several layers in QGIS
Again, assuming I understand the question, I think my solution will work. Concatenate your country, nuts1, nuts2 and nuts3 fields into a new field (call it "Split" or whatever you want.) Use this new field to split on.

You can post it publically somewhere (dropbox?) and just link to it here.

comment Convert Graphics to Vector in QGIS
Do you have a sample of the data you could post? I suspect m.cogo can work with a bit of reformatting. Since the exact tool you want doesn't seem to exist, you may have to be a bit flexible in how you format your input data.

comment Convert Graphics to Vector in QGIS
I agree with @underdark that you may be better off generating a vector directly, rather than trying to convert from graphics. Have you taken a look at GRASS' m.cogo tool? You can run it from QGIS via processing. I suspect you could use it to generate a point at the appropriate bearing, then convert the points to lines.

comment Problem with GRASS in QGIS
Can you try importing the geometry only (no attributes), to see if the issue is with the geometry or the attributes (my guess).

comment QGIS I would like to get a single point from a polygon Centroid if within the polygon any point if not
Thanks neuhausr; I'm not sure how to avoid that--I suppose the st_pointonsurface command isn't exactly optimized for what you are trying to do, but I'm not sure what else would be!

comment How to extract mountain peak points from a given digital elevation model?
To improve on method 2) you could also find the highest elevation value in each 'peak' after nulling the lower values, rather than just using the centroid.

comment Georeference image is mirrored
I've seen this too in the past, and would like to hear an answer. If I recall correctly though, it had to do with the CRS not being set properly. Can you confirm that your map CRS is properly set?

It is best to create separate questions for each of your points. It is impossible for anyone to respond to your questions as asked.

comment Import csv file and use “toggle editing” and “field calculator” without Saving it as a Shapefile.
As far as I know, no. It brings it in as a non editable 'virtual layer' - you must save it to an OGR editable file first.
