Biodegradable objects

Random idea. We use Miro for a lot of ideation stuff here. Wailing walls, brainstorming, etc. We’ve found ourselves on numerous occasions wishing for a “degradable” object (like stickies for example). Let’s say we’re in our wailing wall for example, where we “vent” frustration and use dot voting (to say “I too, am frustrated”) to turn frustration into something constructive. I would be awesome if stickies that have no votes would “degrade” over time and eventually disappear, so that we don’t have to manually prune old stuff that we never took action on. Even for backlogs, that tend to just grow and grow, this would be an awesome feature.
