Appearance
Show control unit frames
If supported grid controllers are connected, Playtime usually shows which part of the matrix they are currently controlling by showing a colored frame. You can disable that.
Show column numbers
If enabled, a column number will appear on top of each column.
Disabling this will give you more vertical space, but also hides the shortcut buttons such as Exclusive mode. In that case, you can still change those things in the Column inspector.
Show clip activity
Makes a slot cell light up according to the activity of its clips (e.g. when the clip plays a note).
Depending on color settings, this will be more or less visible. If the cell background is used for displaying the clip progress, it’s not going to make a difference at all.
Show cell selection as cross hair
If enabled, Playtime will not just highlight the currently selected cells but also all other cells which are in the same row and column. Makes it easier to spot the selected cell.
