The new logo looks nice! I was wondering if you could add some additional space around the icon? I mean as it was around the old icon too:

Sure thing, updated it now to include some padding. I went with approximately 6.5% of width/height on each side, which seems close to what some other icons use.

Maybe it could be good to add something along the lines of "please include X% padding around any icon" to the contribution guidelines to keep it consistent for new additions?

[PKief]

Thanks for the adjustments! Just noticed that there's only one thing missing. I usually try to avoid using the colors #000 and #fff as colors. This is because they are either too bright or too dark and the contrast to other icons is too strong. Could you please replace the white color of the drone.svg icon with another color of the blue-grey color?

PS: You're right, I should mention this somewhere in the contribution guide :)

[JonatanLindstrom]

Sure thing, it has been fixed.

Maybe this (as well as the padding mentioned) is a good addition to the contribution guidelines, to help create better pull requests going forward :)

Thanks for providing the new icons, they are looking nice now :)
