Instead closing menu, reopening again, there should be a button on menu that rerolls enchs, and a keybind to automate it, cycle trades mod does that and I believe its pretty neat :3

You can simply take the enchanting item out of its slot and put it back in to recycle enchants. No need for an extra button.

Maybe I'll add an in-game description in the future to make it more obvious that the feature works like this.

thing is you need to move the cursor away from the square, and doing that 50 times to get the enchant kinda gets annoying, a cycling key would be amazing

If you’re really having such a hard time finding a specific enchantment I can only recommend this mod of mine: https://www.curseforge.com/minecraft/mc-mods/enchanting-infuser-fabric
