Currently the program saves its config files on ~/.tixeti/ on linux platforms.
It is somewhat annoying since you see an additional folder on one's home directory.
Can you move the config files in ~/.config/?Most of Linux packages save their personal config data in that directory.

It should be noted that you can only see the .tixati and other app data folders if you are displaying hidden files (eg. ls -a)

On my Fedora-Mate system, most apps actually _don't_ use the .config folder, including gimp, eclipse, java, kompozer, firefox, VirtualBox, vnc, xmms, vice, claws-mail, AndroidStudio, and on and on...

At least at some point in the past, for maximum compatibility with all the different distros, I believe it is/was better to not use .config (it is not always there) and I don't think it is easy or practical to switch now that they already use $HOME/.tixati.  Considering we're talking about a matter of pedantic style preference, and the importance of what else needs to be done, this would be a very frivolous use of the developer's effort.
