#if you're going to get bench storage intentionally though please use those powers wisely

When I was first playing though white palace, I had a glitch where in that room with a bench just above the first fly parkour section and below the big room with loads of sawblades, I was on the bench and still moving while in the charm menu? I don’t have footage cause it was deleted somehow

Sounds like bench storage! i.e., keeping the state of being on a bench while not actually on it. There are a lot of ways of getting it, mostly ones that involve messing with quick map, but you can get it with hazard early control too. It's hard to say how you got it without a video, but here's one way I could see someone getting it accidentally:

[Video ID: Gameplay footage of the player in White Palace. The player falls on top of a Wingmould to get double hit into thorns and immediately dashes to the bench and opens inventory. They begin moving around off of the bench, still in a sitting state with inventory open, and equip a few charms. Their inventory automatically closes as they enter the room above. They go through the first platforming section of the room, then begin charging Crystal Heart on one of the platforms but open inventory and let go of Crystal Heart before it's fully charged. They equip a few more charms and overcharm Hiveblood with their jump key, and can be seen jumping up and down behind the charm menu as they spam the button. /End ID]

If you closed inventory and left the sitting state before you entered another room, the effects of the glitch wouldn't persist. As you can see, leaving the room with inventory open would have let the state persist indefinitely (until you bench next that is).

The persistent version of bench storage has some funny effects like letting you equip charms while off of the bench, but you're also in a glitched state where you can softlock just by opening inventory. Opening inventory always takes away control, but with bench storage, the game doesn't know to give it back. That's why I charge cdash before opening inventory towards the end, and then release it to tell the game to give control back. Fun stuff!
