In my opinion, Mojang should consider adding the Saved Toolbars feature to Creative Mode on Minecraft: Bedrock Edition. This would allow users to save their toolbars and retrieve them easily, just like in Minecraft: Java Edition. Having this feature would be especially helpful for content creators! It would also help provide more parity with Minecraft: Java Edition. I suggested the idea for Minecraft: Bedrock Edition years ago through the feedback page, but nothing ever came of it. For anyone who is curious, the link to my post on the feedback page is below.
