That would be a nice addition, I attempted to right click save images to import into inkscape and stack them myself with transparency but I couldn't. Normally I would just printscreen then cut and paste through paint and then import but Im using a new laptop with compact keyboard(while I drink my coffee and wake up) and cant find the prntscrn function key through the rainbow backlight.
I would think adding multiple options would be best but then again if You did open it up, You may also run into people using the forum for unrelated or malicious files.
On a side note, I recently acquired an Ortur laser master 2 pro and a 6040 CNC desktop router and am building a tool chain for small scale, high turn around PCB production (Mainly for my own personal us but would be willing to share out a portion of my eventual production capacity). I would imagine there are many other people doing the same thing and that may be another resource your site may want to investigate. Especially given the ever growing shipping times for overseas products.
