INTRODUCING THE MONERODO OS
http://nodebox.link/What is it? Monerodo is a portmanteau (because I love them and love that word) of Monero and Node (well, esperanto for node).
Now you can take any old PC and turn it into a monero node, monero pool server, and nvidia miner. Instructions on the website.

Its not a GUI... but its not CLI either!!!!
Excellent!
a new option could perhaps be added : Restore your accounts from MyMonero seed
i tried it and i was able to restore a wallet from a 12 words seed from MyMonero (the thirteenth word is unused, checksum only)
the test code is here:
https://github.com/Arux-BTT/bitmonero.gitgit clone https://github.com/Arux-BTT/bitmonero.git MyMonero_seed_import
cd MyMonero_seed_import
git checkout MyMonero_seed_import
make release
then a simplewallet compatible with mymonero seed will be able into build/release/bin as usual.
./simplewallet --restore-deterministic-wallet
follow instructions and type the twelve first words of your mymonero seed (not the thirteenth)
at the end, simplewallet will crash (core dumped) but no matter, wallet is successfully creating.
the mymonero seed:

simplewallet in action: (notice that the last word ("poker" in this example) is missing, seed is twelve words only)

it's crashing but a relaunch later:

funds are spent without MyMonero
a little bug with viewkey command:

a bash script could certainly automate it.
