I often use OP-Amp’s - usually LM358, MCP6002 and MC1458.
These are DIP8’s with similar Pinouts and Performance.
Most of the time, I use only one Channel, thus I made a Part without the 3-unused pins.
This provides extra space for routing…
I spent a good amount of time discovering the tricks to using Gravit Designer and, while it has some gotcha’s, it is an absolutely perfect fit for my Fritzing Part and PCB making! Just need to learn the tricks and, perhaps best of all, it provides for Pages and Masters…
So, here’s what I did:
Created a single Part document that contains Pages for:
Schematic
PCB
Breadboard
Icon
Each has it’s Layers and Elements as required by Fritzing.
Exporting with One-Click saved all Pages to individual SVG files as needed for Fritzing.
Used BBedit as a Text-Editor to delete the lines in XML that caused problem (until they fix that).
FYI - you can use any text-editor on XML, just select the file and ‘Open-With’ the text-editor, as double clicking opens SVG in default program.
Attached are:

Fritzing file
Other than deleting the Vector-Scaling text (until they fix that) I did NOT need to do any XML editing.
Also, though with Inkscape, I had to make Paths, I did not make anything into a Path for this (though, I think I left the file with a Path for the text but, it wasn’t needed)… sooo cool 
All contents are as natively created in Gravit.
Notice there is a Cutout in the PCB. Simple!
For those interested in Gravit, the Part and PCB files are attached - BE SURE to Delete the .fzz
Hopefully the file (done on a Mac) will open in the Window/Linux and other platform versions…
Yes, I like Big contact pads and set the DRC to 0.2mm. I use 1mm diam holes to minimize changing bits on my CNC mil.
