Dear Ankit, I am using Conceal and am quite happy with it. I particularly appreciate semplicity and fastness. I have a few suggestions to improve it:

1) when you move a file to Conceal, the window with password etc is not on the front of the screen: at first trials I tought the software was blocked as I did not notice the dialog window behind explorer window and I had to quit software.
2) if you have to encrypt several files, it can be boring to set similar options for all of them, so I'd like the software to store my preferences in term of encryption options, destination and delete original file. It'd be nice to have a menu with options to set these properties
3) the main window is too large (particularly if you have several open windows) and cannot be resized.

I noticed you have English and German version, if you wish I'm ready to make Italian translation.

Thanks for your job and regards
Aldo
