Try old hover design

[jasmussen]

There has been discussion on the heaviness of the blocks. Initially this led us to having only the left border on hover. We added a full outline so as to better portray that a paragraph is a block.

However multi selection across blocks works well. If we can get it to work as well with keyboard shortcuts (and show list and quote options in a toolbar), aside from this addressing #539, it seems like there's less of a need for the block outlines to look so heavy.

I like this change personally. The one instance where it looked a little different to me was when a neighboring block is selected, and I hover over the next... something about the full square outline next to the single line on the left.

The other item, though not related to these changes, is the block settings/delete shortcuts feel a bit "heavier" with this change since there is no line along side of these controls they seem extra bold to me.

Great feedback, Timmy. I agree, that's the biggest weakness of this. However the items on the side in general bug me — I know why they're there and what value they bring, but they contribute to the heaviness of the UI. See also #2156

Another option — what if we show the cog and trash button only when you are hovering the right area?

That is:

• When hovering an unselected block on the center, you get the left border and the up/down arrows
• When hovering the right edge of an unselected block, the cog and trash show up (obv. also on focus)
• When a block is selected, they all show up

Perhaps worth trying before we try moving the cog and trash to the quick toolbar. It feels like there's value in being able to hover and click to remove a block.

Not sure, discoverability might be a problem. I'd rather keep it simple.

Closing this branch as other efforts are underway.
