I hate all of this stuff and it is greatly saddening that browser vendors are not protecting us from it. It's like the pop-up-on-click days of old and it must stop.
If I select some text and copy it, I am taking a very explicit action. I am giving the computer a very explicit instruction. There is no room for interpretation. It must not disobey me!
From the point of view of the browser, it very explicitly does what you told it to, without interpretation, obediently. The problem is that yours and the browser's opinions differ on what you intended to do.
Why, no, not the same.
I think it is ok for a webapp to be aware that I selected some text, and which text, so a further click on "boldface" would have a context.
But it is not ok for a webapp to interfere with the text selection itself.
For instance, well-intentionned chrome always add "http:// when I select the url. It gets in my way very often and it is not what I intended: I did select google.com with my mouse very carefully, I do not want Chrome to be clever and add "http://. By the way, this issues comes from the excessively minimal UI: Chrome should not hide "http:// in the url bar, point-barre.
I do not use Evernote because it messes with my selections.
I have to use Trello at work but this bully don't even let me select a card title.
And the list goes...
It does if the card is open, are you referring to it assuming you're trying to drag a card on the board view? I'd rather have that than sometimes it drags, sometimes it selects the text.
If ever there were a company that just needed to be nuked from orbit, it's tynt.
