I know, but the most sensible behavior should be the default.

> last big discussion we had about this here:

Interesting. The arguments in favour of double click are overwelmingly stronger
than those in favour of single-click, yet you chose single click.

> I know it's not what you expect, and not what anyone else does

That's the definition of a right default: what anyone would expect. So you know
this is a wrong default.

>From the linked discussion:

> Advantages of status quo (single-click to open)
> - Makes opening files and folders much easier for users with poor dexterity or mousing 
>   skills

Good point. However, that's a minority and therefore they should be the ones
who go to Settings and change the behavior. We don't make huge fonts a default
for the benefit of the visually impaired, or high-contrast black-and-white
themes for color-blind people, do we? We make those options available to them
to choose.


> laptop trackpads

That is the only single one point that is somewhat valid. Actually I avoid
trackpads altogether and always bring a mouse wherever I bring my laptop,
because trackpads are crap anyway.
However, it is just one somewhat-valid argument vs many against. And not that
great of a point either, because double-clicking on a trackpad (using the
physical button) is not really that hard.



> More intuitive; many users on other platforms have never fully understood when they need to double-click, and end up cringe-inducingly double-clicking everything "just to be safe."

LOL I'd like to see some data backing up the "many users" claim. Yes I have
seen such users. Those are people that don't know how to operate a computer at
the most basic level. It's easy to understand when you need to click and when
you need to double click. Because there are some people who are very clumsy
with computers doesn't mean that something is not intuitive.

It's not worth to make it ridiculously difficult to select things just because
there is a minority of people who don't understand how double click works.


> touchscreens in particular [...]
> More consistent with mobile [...] Vastly more touch-friendly

You are doing it backwards. You are trying to make the developer's life easier,
not the user's.

That reasoning is flawed. You are saying:
- I have this behavior (the traditional one, double-click based) that works
wonderfully with mice and non-touch screens
- I transpose it literally to touch-screens in the most literal way, without
putting any thought into it, click once => touch once; click twice => touch
twice
- This way, the resulting behavior on touch screen sucks
=> hence you deduce the starting behavior is not good.

No, what is not good is your choice to map one click to one touch and N clicks
to N touchs.
Maybe you need to improve the way you map a mouse-based behavior to a
touch-screen behavior.

Think of right-clicks. Touch screens don't have a right button. Does that mean
that we should eliminate right-click altogether? Fortunately, people who
designed touchscreen-based interfaces in the early days weren't that stupid.
They came up with the idea of mapping right-click to long press. 

The well-established convention on mouse-and-monitor interfaces works well,
it's intuitive and doesn't need to be changed. What you need to figure out is
how to map it to a touch screen.

Obviously, the action of opening (the one that in the traditional world is
accomplished with a double click), needs to be a single touch on a touch
screen. So the question is how to perform selection on a touch screen. It's not
trivial, I know. You haven't solved it anyway by adopting single-click. You
have just created the same problem on desktop.

You had:
- desktop:
  - single click selects
  - double click opens
- touchscreen:
  - single touch opens
  -what do I do to select??

Now you have
- desktop:
  - single click opens
  - what do I do to select??
- touchscreen:
  - single touch opens
  - what do I do to select??

Yes, you made it more consistent, I give you that. By breaking it where it
already worked fine.
