I do think maybe that if you're talking about x-plane frequency changing, that may be being done at inappropriate times.. in the simulator. IRL, there's no frequency changes once in the airport area airspace, on approach, etc. only frequency change is after landing, switching from tower to ground. the handoff from approach control to tower is usually after established-on-final, prior to FAF. and for that you're exactly right, you have the digital flip-flop for those.
Are you talking about the Audio panel? for which COM channel is active? 1or2.
When time to switch COM frequencies, approach control to tower, digi-flip-flop COM1. In my personal experience, the audio panel is among the least used item, used mostly/only for navaid audio ID, and secondary COM channel like ATIS/AWOS on COM2. Live communications only on COM1, and flip flop those. The risk of "lost com" is made much worse by adding in which audio channel is lined up on the audio-panel.
(different people may have a different workflow and prefer com channel switching.
in that case, they're entirely welcome to swap transponder and audio panel)
Maybe we just have difference of opinion about what belongs where and why.
That's okay.
My workflow is live communications on COM1, retune or flip-flop. ATIS/AWOS on COM2.
Never mixing up where live communication is at. and on COM1. there is present/future, or present/past.
in either case there are valid go-back options for an onset of "lost communication" situation.
There should never be any frequency switching in the critical phase of flight. inside FAF, less than 1000', in the pattern, etc. any frequency changes are outside of critical-phase-of-flight, turned off for a departure, clear on course contact departure control. etc. and those are flip-flop COM1 or re-tune based on written down Freq# on paper in order of freq# assigned/received. Just my workflow, I'd personally never put a live communication channel on COM2. I have similar OCD about navaids, and which is on which NAV1 or NAV2. It's all intended to relieve mental workload by logical processes and lineups. e.g. never fly an instrument approach, primary navigation guidance, on secondary navigation faculties.
primary-primary, secondary-secondary.
But you know, everyone learns the way they do, knows things how they do, has their workflow that works for them. that's totally and entirely expected and ok.
LFX/LJX, this view at also 90° FOV, everything needed here. only thing not in view is audio_panel.
if audio_identifying the morse code of a navaid, is a head-down, listen, and finger on the dot-dot-dash code on the approach_plate.

the axiom in aviation is;
aviate, navigate, communicate.
in that order. in that logic. transponder tuned/on/mode_c, supersedes communicate.
- in-flight, eyes down, full view. including map and next_level engine instruments.
- audio_panel, there near the right hand on the levers. fingertip distance for done-by-feel buttons, IRL, in theory. for much the same "in-the-office" time during navigating for changing to listen to NAV frequency to identify the navaid dot-dot-dash morse code, and then deliberately back to COM. Similarly down in the in-the-office position for while outside of the approach area, switching to COM2 to get ATIS/AWOS, write it down, and then deliberately back to COM1 for live ATC communication, toggled between approach-tower. tower-ground. tower-departure. in the eyes-up, flip flop on G430#1.
