It allows remapping of all keys. Updates will come for better key injection support, long presses, more keys, IP / Port input in app, multiple configurations etc...
To set your Vita's IP / Port, edit config.cfg.msd, you can also set the KeyRepeat here.
To edit keys, hover a Vita button in client and click the blue bubble, while it's red, press a new key.
You can save now your config with "Save button"
