I now this has been requested for the old table, but I am adding it specifically for the new table and providing a solid use case.
I have added quit a few Actions to this one table:
I need to add a couple more and this starting to get a tad ridiculous!
A drop down menu would be much more useful especially if it could include text, icons, coloring, spacers and all the usual context menu like bells and whistles.
This is definitely a valid use case & something that we're thinking about for the new table
