Suggested change

	labNotes->setText(tr("Use ctrl+a to select all sets in the view.") + "<br><b>" + tr("Deck Editor") + ":</b> " +
	labNotes->setText(tr("Use CTRL+A to select all sets in the view.") + "<br><b>" + tr("Deck Editor") + ":</b> " +

Regarding all hintsGrid:
Don't you think the extra line breaks were useful?
Because of how lists are displayed you now have two blocks, but the second block being bullet points of the last element of the first block. The connection and context is not as clear now as seen in your screen.

Compared to what is currently in client:

I wanted to make it smaller, it's taking up a lot of space

[tooomm]

I see, sure. Both not ideal. :)

[ebbit1q]

I made the dialog hint a little smaller again

[ebbit1q]

in order to make the list smaller I stopped disabled sets from being used for image art, this resulted in a >1% performance increase as shown with the added timer

[ebbit1q]

I removed a few needless entries to the server dialog settings, among which a password entry that saves the password you used last in the register or recover dialog, whether you want it or not............
None of these entries are used anymore since the new login dialog was added, even though they all accounted for entries to be used by the old dialog they now do nothing.
Its possible to adjust these changes to try to mess with the new login dialog but imo it's not worth it because it doesn't in the current state.
I also fixed the remove function, which used to remove an entry but not move all other entries back by one.
