Increasing a bit the bottom margin for the confirmation dialogs
Changed the color for the guidedActionConfirm dialog to the palette’s alertColor
Disabled onHeightChanged on ToolStrip for the time being as it was not working. I need to come back to this and see why it hides “optional elements” even though I have plenty of space for them.
Adjusted the color for disabled text so you can read it within the ToolStrip
