This is a great start!

• [x] The "properties" button text is very small - this needs to be bigger, and should be "Process Properties".
• [x] The button should also have an outline to make it clear that it is a clickable button.
• [x] We should be able to right click on a row in the "Products" table and get a similar properties table for that specific product (you can use bw2data.get_node() to get the product object and retrieve its properties). I don't think we need to cache the properties for each row, we can generate this on demand by querying the database.

@zoltanszocs Looking good, and the functionality works as expected. Please see my earlier comments on the next set of things to work on. Thanks!

• [x] @cmutel need to fix https://github.com/brightway-lca/brightway2-data/issues/182

Great; let's add a bit and then we can merge this and do the next stage.

• [x] 1. Please move the "Properties" button from the right to the left, right after the graph traversal button.
• [x] 2. I added a column "Functional" to the products table in https://github.com/cauldron/activity-browser/pull/42/commits/59eddc29946fb1e99cc1b3edf8b009255f52667b; this needs to be improved by moving from StringDelegate to BooleanDelegate (not yet defined), which should display with some subtle color coding (i.e. a little bit of green or red).
• [x] 3. @cmutel Add a column for default allocation factor. Blocked currently by https://github.com/brightway-lca/multifunctional/issues/19.

We need one more big step here: If I understand correctly, we have a property editor for the current process or product being viewed, and the ability to edit the properties of the products or processes being linked to. However, we also need to be able to edit the edges (called Exchanges in the codebase). So this menu:

Needs to have two options: "Node properties" and "Edge properties", with the code saving to either the appropriate Node object, or to the Edge.
