UPDATED FOR BLENDER 5 LTS!
There is one glaring issue from Blender 4.2 onwards—bloom is now no longer one click! Well, this add-on / extension solves this issue.

[Updated December 6th, 2025] Now supports Blender 5 - Free update for all existing users!

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

That's one blooming problem solved! The Render View button will automatically turn on the effect. HAH enough of the puns, I hope you enjoy it, let me know if you have any feedback.
