This is really helpful for me.

Great feature !!!
Highly appreciate the new features in a new upgrade.
What if there can be a search function that can be done by voice commands so that for a user who cannot write or who is disabled can give voice commands to find the content of the document.
Same goes with the "support website" also if you guys can do that.
Thanks. 

Great work done

Good to have new feature.

one thing to mention:

Hedex should contain some Basic theory of GSM/UMTS. if we search Channel concepts of GSM/UMTS we only find some product based working principle.

 To develop a good concept of product we need generic technology concept so that we can deal with any vendor product.

Very good function to find document. This will make us easy to find particular documents.Thank You.

It was a much needed upgrade.. especially the GUI.. makes searching available on the same screen.

Your Hardwork help us a lot.. Thanks a Ton..
