P: Quick Export option to disable transparency trimming

yes plenty of workarounds, scripts, hidden geometry, hidden masks, actions, plug-ins etc. That is not really the point. JUST FIX the feature  so it can be used by, I guess, the majority of people. Little option ON/OFF. That is all we need.... 

at least an acknowledgement from Adobe that we have been heard...

This idea/feature request has been open for 10 years.

So the point is that if you want something now (or a decade ago), there are alternatives to waiting.

but the Quick Export is great for a single layer and you get the layer name also. I would be my primary PNG save almost EVERY TIME except it is... alas... not... because it remains broken

By @Brad5E0E 

This would currently require a script as a workaround, which could be triggered via a custom keyboard shortcut.

10 years and still no option? Really. smh.

All the workarounds and other ways to save are fine, but the Quick Export is great for a single layer and you get the layer name also. It would be my primary PNG save almost EVERY TIME except it is... alas... not... because it remains broken. Did I mention 10 years we have been asking for about 10 lines of code to be added to PREFS.

Another workaround is using File>Generate>Image Assets and maintaining your layer structure like this:

Here I used canvas size masks on the groups with .png extensions. Just ctrl+A and add mask to group.

Here is the result. Images will be generated automatically.

It is faster than quick export for my workflow setup correctly.

I can explain better if it is not understandable.

I've spend several hours last night adding almost invisible pixels to layers just to make sure they don't get cropped upon export.

This can be automated via an action or a script:

/*
Transparency Bounding Pixels.jsx
Stephen Marsh
Version 1, 22nd September 2021
Adds a 1% white pixel to the upper left and lower right corners of the open document
Note: Assumes that the active layer is a raster layer can be filled!

I agree! We need this feature!!

I've spend several hours last night adding almost invisible pixels to layers just to make sure they don't get cropped upon export. The layer-mask hack didn't work anymore (although it DID work for me in the past, apparently they "fixed" that in a recent update).

Adobe, isn't Photoshop meant to be THE tool for professionals anymore? The gold standard? Why do you make people beg for years for the most basic features to work the way one would expect them to work? Why do you keep on including useless "content aware" toys instead of fixing the tools we're using to get the actual work done?

+1
I agree that this feature missing is not so much just one less nice-to-have, as a crucial omission.
