I didn’t say it’s laziness nor did I claim that to be the case! Trust me, I would have said so in the first place!
I’m just stating that it’s such a small feature that you can do it yourself. Also, what should be displayed is open-ended, so however you design it you have the flexibility of doing it whatever way you want. Because of the said open-endedness, if it were up to me, I’d see the request as just because other frameworks do it doesn’t mean JUCE should necessarily: users can desire however many number of things to be shown in there and stylised however many ways.
