"Just"...

But yes, I almost always use miller columns to browse the file system on OSX. This way any folder is both select and opened on a single click.

Miller columns are great and should be implemented everywhere. Imagine how good they would be for navigating large websites.

Yes, 'just'. Do you not always have at least one hand on the keyboard?

I'm not familar with Miller columns, but if you're changing the behaviour of your file browser, then I'm not sure why you're suprised single click might not work as intended.

No I don't. And I think that people who aren't developers have workflows where they use the mouse a ton and the keyboard less.

Miller columns have been one of the default views in OSX Finder for about two decades, opening and selecting at the same time is how they are supposed to work. Here's a demo video: https://www.youtube.com/watch?v=yQ7trdpY9MI

I think miller columns was part of KDE file manager for some time, before they decided they were too complicated for developers.

I don't really understand where you would put your hand instead. In your lap? Why not have it on the keyboard?

Ok, I see what you mean by Miller columns now. I guess I wouldn't consider that image preview on ths side 'opened' though. 'Opened' to me would mean launching a dedicated image viewer with that file.

I mean, there's a reason why the default in most operating systems is a double click. Having to combine keyboard and mouse gestures is weird and hard to remember for most users.

When using miller columns in Finder, you will open a folder at the same time as you're selecting it. Files will only preview.

Well, that's why Plasma has that box I mentioned, so you can select without using the keyboard. But selecting multiple files requires you to press CTRL anyways, so I'm not sure why it why you think it would be weird to use CTRL for just one file.
