at this point that missing option to make the taskbar two rows tall, and add quick launch to it. those are the reasons why i have not even entertained the idea of updating to windows 11 yet.
yeah pinning apps to taskbar since windows 7 has kinda served the same purpose, but it gets messy as there is often situations where i use apps what i don't think deserves to be pinned. so it quickly is just a cluttered mess of apps, and instead of making stuff easier, that app pinning just messes it up more.
those two things are literally the only things that i would need your app to do.
