Please add "Ignore Mute" switch – m48 Review

I enjoy the app. I wish it had one thing ... an "Ignore Mute" switch in settings. My 41CX app has this feature. For those of us who keep our phone in silent mode, the "Ignore Mute" switch allows the calculator sounds to still work. Silent mode is mainly used for unexpected sounds such as ringing phone, etc. However, when using calculator, all key sounds are fully expected. The key sounds are, in fact, extremely useful as feedback since there is no tactile feedback. As a silent mode user, I currently must turn on sounds each time I use the calculator and then turn off when I'm done (hopefully not forgetting to turn off). The "Ignore Mute" switch would eliminate the need for turning phone sounds on and off. Thanks.
