"Children" and "Parent" navigation

[EverSalazar]

It would be good that cards with children are immediately identifiable and that you can expand them with one click (right now, you need to make two clicks in order to expand)

Would something like this be obvious enough?

I think the icon for children needs to be directly along the line and not departing from it, since the children include the ones already in display (the branch with the number 17). Something like the rightmost one is what I would lean towards:

I even added an icon on top to automatically show the direct parent of the specific card. That way you could navigate the tree by one-clicks displaying parents and children. Also, when there are more than 3 children, maybe the icon can show a drop-down menu?

I don't want to clutter the screen, though. And I can see how adding these icons can visually clutter something that currently looks really nice. I'm wondering if we could hide those icons by default and show them when you hover near that card and also adding a toggle button to always show them?

I'm going to remove the priority tag from this issue, since the latest commit, seems to be doing the work just fine. I'll leave the issue open, since we might want to discuss this further later

A comment from David that I think is related to this:

Im not sure this problem is easily solvable, but we currently dont have a good way to distinguish between species, subspecies, genus, etc. in the “children” section, which makes it a little hard to navigate. Maybe we can weight it toward species somehow?

I think he's confused about what the list of children are. Maybe he thinks it is listing also grandchildren, when it only displays direct children. I think that a set of buttons like these can help:

[EverSalazar]

OOOOOORRRRR, maybe those buttons are displayed on top of the card when you hover over them? That would make it difficult for touch-devices... but what I am proposing up there would generate a lot of visual clutter and I wouldn't like that...

Sorry for the spam... but here's another comment from David that is related, I think:

Right now, there are lots of unsatisfying searches. For example, if you search for “dog” you can get a box for “Canis lupus familiaris” but clicking on the “37” box above it doesnt lead you anywhere useful and you have to click around a lot to find relatives.

Also, Alex didn't quite understood at first sight what the numbers meant. He only figured it out after playing a bit and undo/redo to see what had changed.

What David didn't understand here was that the species listed at the bottom where the most recent ancestor and the ones at the top were the least recent. Not sure if we can convey that easily, but a "parent" button will help a lot, since people would mainly use it for navigate directly to the parent.
