Laurent (ID: 00000014da76b9dc) Voted 4 ★ - Updated 07/01/2023 The application is very useful, fortunately it exists but it is a shame to have to install an extension to have this functionality. However, it lacks a sound option: that the notification can be permanent or in any case lasts longer. Indeed, if I am no longer in front of my chromebook, I do not perceive the notification at the risk that the next time I use it, the chromebook is turned off because the battery has been drained.

Christophe Schouwey (ID: 00000024ef183e24) Voted 1 ★ - Updated 05/15/2023 RIDICULOUSLY SMALL I just want the battery status to be visible all time, large enough for me not to have to blink.

Thanh Huynh (ID: 000000da9edf63a5) Voted 4 ★ - Updated 03/11/2023 This is a great extension. To avoid missing important notifications, such as when to connect/disconnect the charger, I would like to suggest the following configurable options for each custom notification : 1. Sticky popup window (not a page) 2. Continuous sound which stops when the charger is plugged in/unplugged or when the user disable it Thank you

Fabrianne Morales (ID: 0000005a40001f58) Voted 5 ★ - Updated 10/29/2022 Exactly what I need - customizable battery level alerts. Would be extra brilliant if it comes with audible notifications. :)

Dr. Andreas Leo Faulstich (ID: 000000bf5d4ba8b9) Voted 5 ★ - Updated 06/09/2022 Battery Status enables me to set notifications for battery levels. So I have set some low battery notifications to be not surprised by my Chromebook suddenly shutting down with an empty battery just because I forgot to plug it in.
