Thanks for this extensive feedback! There are many great suggestions. I have recently started a separate thread regarding the use of docks. You may want to discuss this particular aspect there.
I absolutely agree. I really hope that VPN clients will be made available through the Software Boutique soon.
Regarding new suggestions it is best to start a new thread on each program that you would like to have included with your own screenshots and your own evaluation/description. You can also add the boutique tag and see how others have done it.
I hope that new and more polished theme options will be available by default. I like the new Mint-Y themes a lot.
