In version 12 pressing "backspace" while typing the database name in the "Edit Project" screen clears out the database name completely instead of just deleting the last character.

Made a typo while typing in the database name? Too bad, you'll have to type the whole thing again after pressing Backspace. Constantly switch between servers with thousands of databases with similar, but slightly different names? The Database textbox is nearly impossible to use until the database list in the drop-down is fully loaded (which can take a while) because when you go to backspace, it just wipes the text without letting you alter the database name slightly.
