I would like to import more "insect" parts ... but i have to draw them before :D
You can import parts in the graphs folder.
There a 5 tabs in the apps, each tab loads part according to their number.
10.png to 49.png (50 to 99, 100 to 149 ...)
For exemple "Structure" tab automatically loads parts names from 150.png to 199.png (183 to 199 are not done yet)
