There is one glaring issue with Blender 4.2, bloom is now no longer one click.

Well, this add-on / extension solves this issue.

With one click you can now enable Bloom for Eevee and Cycles!

That's one blooming problem solved!

The Render View botton will automatically turn on the effect.

HAH enough of the puns, I hope you enjoy it, let me know if you have any feedback.
