Hi guys,

The good news is that I should get the new sensors next week. And the very good news is that I made some good progress with the GUI, as you can see it looks quite good now:

Using Gtkmm in pure C++ was a bit tedious, so I gave Glade a go, and fortunately it happens to be very easy to use.

Unfortunately, that will lead to some changes, as a reorganization of the code will be necessary in order to handle the events and windows properly. However, that's a very small sacrifice compared to the time I saved by using Glade. Plus, once the new code's been implemented, everything is going to become a lot easier.

Cheers.
