Hi Felgo,
I have a potential bug.
Nothing really big but would be worth to inform you if you are not aware.
On Linux desktop, using desktop kit and standard development flow, app always starts in the left side of the screen.
Looks like vertical offset is kept but horizontal is always zero.
There is no issue with Felgo Live server though, here all coordinates are saved nicely between app restarts.
Mint 18.3, KDE 5.8.8, 64 bit
