If you just move the text around (like say a pin number or label) without editing the text, Inkscape slips in a ‘px’ on the font size. If you change/edit text (like say the symbol label), then move the text around, everything is fine. The problem is when you create a symbol and then further edit the text of the symbol. I have also just noticed another problem that is pretty much out of my control and I don’t think I can really fix it. I could remove it as an option and just automatically create the terminalIds.

If you always want terminalIds, check the box once and never touch it again. This is the way it is with Inkscape, it always remembers the last settings made, but this shouldn’t be a problem. At present is seems to remember the last value set. One change that would be useful if possible is to default the Connector terminalIds to always enabled by default. For instance the schematic of the CubeCell part I made this morning was done with this extension. For complex schematics I still tend to use my template files and manually edit the svg (but I cheat and have unreleased python scripts that will define the connector boiler plate too), but for the simple ones I use this, as it is easier.

PCB and breadboard could be done (and I guess may get done) but they are much more difficult than schematic which is more structured than the other two. There needs to be sufficient space in the initial rectangle for all the pins, or an error message will come up when you define try and define the pins, and that can’t be changed due to an Inkscape limitation (as I understand it, it defines the rectangle and then calls the pin creation code with the rectangle predefined.) I already asked about this when I was testing the plug in for him.

The pin numbers need to be in sequential order however so the default Sequential is preferred (and thus the default.) Inkscape will deal with duplicate pin numbers (unfortunately by reverting the previous definition to linexx from connectorxx thus undefining the previous pin, but there won’t be a dup!) There are limitations on what Inkscape will do. To avoid that you need to select “Pin Numbering User Defined” instead of the default Sequential in the Schematic Connectors pane. The way this is done, I can tell you how many pins I want on each side but you choose the pin number.
