Improvement: Button Flip horizontally in all editors.

The song editor has a very useful tool and it is the option to '' flip horizontally '', which basically would function as a '' reverse '' effect. is activated by this button:


For example: If it were implemented in the piano roll editor it would look like this:


This is a progression of chords without reverting, without the applied effect, but with the implementation of reverse button the applied effect would look like this:


If this tool is applied within the other editors, it would look like this:



Also it would work with sample track here it mensiono: #4992

This tool would work very well in the other editors, because it would allow us to flip the notes, patterns and tco horizontally and in this way we would get a "reverse" effect. Regards

Start by comparing the existing horizontal-flip control in the song editor with the piano roll, song, pattern, and sample-track editors referenced in the issue. Review issue #4992 for the related sample-track context. Done means the reverse effect is available consistently for notes, patterns, and TCOs in the requested editors, with behavior matching the existing control.
