Two screenshots of what I've been busy with for my NXT Solaris client. To be released over the weekend, since I need a rest.

Killer!
Any news on how to make this kind of open-source for trustfulness?
Define "kind of open source". :-)
It already is partial open source. Full open source is not going to happen.
My take on this: Define how much you are willing to risk based on the level of trust that you have for a software. Only enter account secrets for accounts that have assets that matches your level of trust and accepted risk, e.g. create small asset accounts with another software and only enter secrets for these small stake accounts in my software. You could still use the "view only" functionality for your big stake accounts in my client and of course all other functions that don't require you to enter a secret.
If we rise funds for this project, is any chance that it could be open source?
I'm sure the community is happy to pay you for this great work (I will personally add funds), but we will need this 100% open source.
Even if it is sexy is no point using it if I can find another client 100% open source.
I think the problem was (not sure if its this client or not) that the program used to write it could not be open sourced due to the libraries used. So without an entire re-write, it wouldn't be possible.
