OSD for battery?

I hardly ever notice that my wireless Mamba mouse is blinking red when the battery is low. It would be really helpful if Synapse offered a way to make an On Screen Display warning for a low battery, or an OSD indicator for battery percentage, even if they are docked in the taskbar someplace. Wireless headphones have the OSD for mic/speaker volume, but they also need a battery indicator.

Can we get this in a future update please?
