In what other circumstance can you delete something by hovering over it?
You mean, hover and hit Delete while an item is highlighted.
I've seen combo boxes that keep a typing history do that, browser Favorites (I think IE might've done that at one point if it's not still there)...it's not entirely new. But you're right, it's not very "discoverable"...but when you see in action, you kinda start expecting it to be supported everywhere else. I try to make a point in my own apps to add this where it's appropriate.
Sounds horrendously dangerous to me - especially without any confirmation dialog.
So I'm typing some SQL into a query window - move the mouse "out of the way" so I don't have the pointer over the query text, and hit "delete" because I want to change what I'm typing... wham! Server connection gone. That might be a client's server I'm responsible for administering, but haven't separately saved (written down) the password; now I'm stuffed, especially if it's 11pm on a Saturday night and I need to do maintenance on that server...
If the hover/delete combo is obscure, just how obscure will the documentation be that allows me to disable this "feature"...?
When building a UI, I never provide the ability to delete anything non-trivial without confirmation.
Where have I mentioned there was no confirmation dialog?
Besides...in all use-cases I've implemented this, the removable items only appear as a result of an action like a right-click, which makes the removable item(s) appear; "moving the mouse out of the way" is never enough to make said removable items appear on their own, so what you're describing is rather unlikely to happen.
You want to talk about dangerous - how about you're in the middle of typing a long paragraph of text, then some random Windows message pops up, defaulting with the focus on OK, and you happen to hit Space or Enter as you continue typing (before you might not even have realized something came up and stole focus away). The dialog box thinks you've confirmed the action it was asking of you, but it was on the screen for such a short amount of time you have no idea what it said or where it even came from. True story, and I can confirm it's happened to me repeatedly.
I was elaborating on a direct response to the message where I said I try to implement the same. If SSMS doesn't prompt for confirmation when deleting something important, then that's its problem, not mine.
It turns out you can just open the list, hover over a server name and press delete on your keyboard and it'll be gone (without warning).
I interpreted the "without warning" bit as meaning there's no confirmation prompt...? You mentioned you were adding the same functionality in your own apps... but clearly you're implementing an improvement over Microsoft's attempt!
I had a similary discovery, that if you open the Alt-Tab panel of running programs, and keep the Alt key down, you can with your mouse close all those windows that you no longer need by mouse clicking their upper right hand X. It may have been around for many years, but I discovered it a few months ago.
The connection settings are held in a dictionary, so you can easily use the REMOVE method to pick things out of that list; then serialise to file to persist any changes.
Not quite as easy as deleting through the UI; but useful if you wanted to automate the management of this list in some way (e.g. have scripts preset to change the list according to which system/client you're working with).
What do you mean Mr McGee? And why are you wearing a Raspberry Beret?
