I had install 1.0.0 as built by Fedora Linux.
I would like to contribute with several parts, yet i can not find a hidden ./fritzing folder in ./home/myself, so i can see the SVGs and edit them.
Speaking of SVGs, can i edit them on an app like Inkscape?
Depends on what parts you want. The core parts are generally in a directory called fritzing-parts in the same directory as the Fritzing executable (although the Fedora folks may have moved that.) The easiest way to get parts is likely to start Fritzing and right click on the part in a parts bin or in a sketch then select edit part (new parts editor) from there
