Hi LightDot! I very much appreciate you packaging tg for Arch Linux (actually I always admired the level technical expertise of Arch Linux users). CentOS and Fedora would also be extremely welcome additions for me, in particular considering that deb (which tg already has) and rpm packages will cover most Linux pc users. I would be glad to link or host rpm packages for tg on my download page (https://tg.ciovil.li) if you agree. Also, if you need any help, feel free to contact me, or to submit feature/pull requests on github.
Yesterday, I received a user manual for tg written by a member of this forum (to whom I am very grateful for this contribution). I still have to take a look at it, but I am confident that he will soon make it publicly available!
On the development side, I am working on a save/snapshot/print feature. To be implemented properly, this feature required a relatively extensive rearrangement of the source code, but, time permitting, it will be ready sooner or later.
