i’m a little unsure of which dialog box you’re referring to. When you say “channels” do you mean track?
Those options of fader and metering positions are within a context menu, which conventionally close upon selection of an item. No doubt inherited by OS treatment of menus. The only case where i’ve seen an alternate behaviour is in FL Studio, where a right-click on menu items selects the entry and maintains the menu’s open state.
Perhaps new options in the Track Properties dialog would be convenient. Those options being metering and fader positioning. That said, Podium allows metering and a fader on every slot, from instrument, through effects, and the track itself. So, inclusion in Track Properties may be misconstrued as having those functions confined to one set per track.
Perhaps, then, the matrix displayed on the mixer could be replicated on tracks.
