Pins instead of discs for tasks with status: "pending"

[jgaehring]

Implement the farmOS status attribute on the log entities being used for tasks. Then distinguish them visually on the canvas.

On the original whiteboard, completed tasks are displayed with a broad, magnetic disc, while the pending tasks are represented by an upright magnetic pin. I see a few simple ways to go about this here:

1. Use large, circular discs for completed tasks, and small circular pins for pending.
2. Use solid, circular discs for completed tasks, and circular rings of the same size for pending.
3. Use large circular discs for completed tasks, and small diamond shaped pins

The second option seems like it would probably be the most visual contrast at a quick glance, especially compared to the first option. Still, I might prefer the first option and keep the second one in reserve for a potential third state, like "in progress," which could be a ring where the center opening would be the same size as the small disc used for pending. The third option seems like it could be the best compromise, because if we do incorporate a third state, it could have a diamond-shaped opening instead of a circular opening, while still keeping a circular outer profile.

Color tone, shading and transparency could also be used to distinguish pins from discs, separately or in combination with the above options, but I fear that would make it harder to distinguish between different operation colors.
