Having a config option for this seems like a poor UI. Instead what would make more sense would be for it to remember the last-viewed tab and open with that. Thankfully... it already does! :)

Unfortunately it forgets the last viewed tab on reboot or logout which makes it broken

I would see the lack of this option as poor UI, as kde is the DE i would expect more options to exist

Ah, we found the real bug. :) I think fixing this makes sense. Not everything needs to be configurable, especially when we can make the default behavior more responsive to user expectations. Preserving state after reboot almost always makes sense.

I guess we will have to agree to disagree about what users expect from a mixer, people expect most mixers to look like the win7 volume mixer widget from the store or kmix.

Many users expect more options to tweak in the Plasma/KDE shell.

Well, most people don't know what a mixer is and just expect a volume control, *possibly* a per-app volume control for really proficient users. It's important that we don't sacrifice the common case for the advanced one. Both are important, and it's the job of good design to accommodate each one without unduly burdening the other.

as an example you might want to look at the mixer transition between windows xp, 7 and 10. and the amount of effort being taken not to upgrade to how the minimalist windows 10 mixer ui which tries to do the right thing but simply confuses by only exposing master volume

the current design is more confusing as devices isnt what they expect nor are the names devices something a non technical user expects. and capture devices are not something the common users can understand without an explanation till they need to use an application that records something

have a system volume and a per app volume is something a user can read and understand

but whats really needed is funding of a UI/UX study.

i disagree about the current defaults but exposing the options to change the applet at least in a kde tweaks app would at least be helpful for power users which are a large part of linux users
