In Horizontal Mode, you can freely rearrange meters by changing the order or popping out any of the meters into their own window.
Open Settings: Click the Settings button found in the Toolbar in MiniMeters.

In the bottom right corner of each meter there are three buttons:

The left arrow and right arrow buttons will swap the meter with the one on either side.
Clicking the middle button (the arrow facing upwards) will remove this meter from the main layout and place it in its own separate window.

To place the meter back in the main layout, click the “Close” button on the popped-out meter.
You can also hide meters you do not wish to see.
Open Settings: Click the Settings button found in the Toolbar in MiniMeters.

Click the Meter: Click the name of the meter you wish to disable. This will hide the meter.

Clicking the name again will enable the meter once again and add it back to the layout.
