Support for per-channel (L/R) ParametricEQ.txt import?

[VacTuzX-dot]

Hi! First off, thanks for FineTune — it's become part of my daily setup.

Question / Request: Does FineTune support importing a ParametricEQ.txt
that contains separate Channel: L and Channel: R sections?

My headphones have a noticeable channel imbalance, so my measurement tool
exports an asymmetric EQ like this:

Channel: L
Preamp: -6.13 dB
Filter 1: ON LSC Fc 105.0 Hz Gain 4.7 dB Q 0.70
Filter 2: ON PK Fc 47.7 Hz Gain 1.4 dB Q 1.04
Filter 3: ON PK Fc 129.7 Hz Gain 0.7 dB Q 1.10
Filter 4: ON PK Fc 1289.8 Hz Gain -0.8 dB Q 0.37
Filter 5: ON PK Fc 3156.1 Hz Gain -0.5 dB Q 6.00
Filter 6: ON PK Fc 3488.9 Hz Gain 0.3 dB Q 5.45
Filter 7: ON PK Fc 5469.3 Hz Gain 0.7 dB Q 2.59
Filter 8: ON PK Fc 6754.7 Hz Gain 1.4 dB Q 5.47
Filter 9: ON PK Fc 7976.7 Hz Gain -1.0 dB Q 1.92
Filter 10: ON HSC Fc 10000.0 Hz Gain -0.1 dB Q 0.70

Channel: R
Preamp: -6.13 dB

What I've observed: When I import this, it looks like the Channel:
lines are ignored and the filters get flattened into a single 10-band EQ
applied to both channels — so the L/R difference is lost.

What I'd love to see:

• Parse Channel: L / Channel: R blocks into two independent filter chains
• A simple Link L/R toggle in the UI (linked by default, so nothing changes
  for existing users), and when unlinked, separate tabs/columns for each channel
• Independent preamp per channel would be a bonus

Why it matters: Channel imbalance is really common on both headphones and
speakers (room asymmetry, driver aging, etc.). Right now the only way to fix it
on macOS is dropping down to AU Lab / Audio Hijack, which is a lot heavier than
just using FineTune.

If per-channel EQ isn't on the roadmap, would it at least be possible to show a
warning on import when a file contains Channel: directives, so users know the
asymmetry is being discarded? That alone would prevent silent misconfiguration.

Happy to test builds. Thanks!
