Ghost notes: Ghost icon inside piano roll.

Nobody has claimed this yet.

Currently to set a piano roll pattern as a ghost, you have to do it from the song editor by clicking left on that pattern and executing the option `` set as ghost in piano-roll ''. good!!.
The problem is that when you modify the same pattern several times (either to make a correction or modify a note), you have to look for it and set it as many times as necessary through that menu option. This sometimes becomes a bit repetitive.

It would be useful to have this option but within the piano roll, (since basically this option `` photographs '' the written notes). something like:
In this way we simplify that task, and every time you make a modification to the pattern you would only have to press that button without leaving the piano roll. Regards.

Start by comparing the piano roll and song editor interactions described in the issue, including the existing “set as ghost” option. Add an equivalent control inside the piano roll so the current pattern can be made a ghost without leaving that editor, and verify that it remains usable after repeated pattern modifications.
