I often need to enter triplets or other tuplets in my tracks, but these are not innate to the ticks-per-row setup of trackers. I'd like to see a Tick Jump setting that allows you to move by ticks when notes are entered or when navigating. When the user enters the first note (presumably quantized to the first tick of the row), the entry pointer moves down the given number of ticks and automatically enters the correct Note Delay amount. This would save me a lot of time calculating the number of ticks within the row to start the triplet note.
When adjusting the Row Jump value, the Tick Jump would also be reset to the correct number of ticks in those rows.
Perhaps a shortcut key toggles between jumping by rows or ticks.
