Short description of error
[Please fill out a short description of the error here]
This is more a UI papercut than a bug.
When you calculate the mass of a rigid body then you will get a popup with a huge list of available items. It is very high and has just one row. In the adjust last operation panel the same list is broken into three rows. This is much handier to use and to read. It would be better when we could have the same popup when activating the tool.
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
Add rigid body. Use calculate mass in the object menu. Watch the popup.
