Buttons and popover buttons in button bars are slightly different to their equivalent objects on the layout.
- It should be possible to specify the name by calculation for [popover-]button also for buttons not in button bars
- It should be possible to drag and drop [popover-]buttons interchangeably between button bars and layouts (bb->bb, bb->lyt, lyt->bb, lyt-lyt)
- It should be possible to change a layout button into a layout popover button, and vice versa.
- Better UX
- more consistent
- user not forced to use a button bar
- Mistakes can be more easily corrected (no Gotcha)
- Less overhead
- Layout is more efficient / faster
- Easier to style buttons without button bars
- Greater productivity
- Correcting accidentally chosen wrong button type
