Nodal workflow for adjustment layers
It seems insane that EVERYTHING you want to do in After Effects relies on the order in the layer stack. It makes sense sometimes, but things like Adjustment Layers where it affects EVERYTHING underneath it is so annoying. You can't even exclude layers from being affected by the Adjustment Layer, which leads to needlessly complicated timelines - and the fact that there's no timeline folder ability (like they have in Illustrator, Photoshop and literally every other compositing software) just makes using AE a drag sometimes. I know I'm wasting my time requesting a feature from Adobe seeing as they seem to despise AE users, but I thought I'd at least try. I look forward to the software not changing for the next 15 years.
