> That said, you CAN still have Ableton's plugins displayed in the manner you prefer. It's a hidden feature that's not documented. Pretty easy to setup, but not discoverable. It's an option that they developed but decided not to include in the final version. Here's a tutorial: sonicbloom.net/en/ableton-live-insider-tips-options-txt-part-1/
I've specifically noted above, expecting this reply: "I'm aware of the Options.txt hack which is unreliable and I'm not even sure it works with the latest Live 10". It does NOT work properly and it's unsupported/unmaintained. You get misaligned circles, up to 4 per channel, instead of plugin names, because redraw logic is broken.
> Having all instruments and plugins in a horizontally-oriented trough allows quick drag-and-drop rearrangement.
That's true in most DAWs. E.g. in Logic, you just drag plugins around, either in the channel strip which would be always open for a given channel, but ALSO in the mixer view. Try dragging plugins across channels in Live and see how that goes for you.
> It allows you to reach the knobs on their native instruments and plugins without the need to open/close plugin windows firs
Same in Bitwig. In Logic, you can't but instead you can e.g. see all (native) EQ curves for all channels simultaneously in the mixer view and access it without having to select the track first.
> MIDI mapping becomes much quicker and intuitive when you can simply toggle the MIDI/Keyboard mapping overlay for a given plugin.
Same in Bitwig. In Logic it's a few clicks instead of one but the idea is the same.
> Being able to nest plugins within them like macros and then quickly hide or reveal a dozen plugins within a single rack is great for declutterring an otherwise busy interface.
True. But that comes at a price of those chains and effects being even LESS discoverable when it comes to mixing. Since now a particular plugin may be buried deep two layers down in a rack of racks.
