sorry, i forgot not everyone knows my channel is bedrock related... although i still meant all of minecraft, which would include java and bedrock...

one entity as opposed to an entire area wouldn't cause more lag at all... if u left an entire area going, u would have multiple entities going... mods dont count as minecraft.. clearly u can have mods for a lot of this but multiple mods can cause many issues together... all of these were clearly meant for regular vanilla minecraft...
and i know if u name mobs they dont despawn... i very clearly stated objects... i for one, along with many people have had issues with minecarts despawning, so the ability to not have ANY OBJECT despawn would be awesome. and the gps aspect would just be a cool feature to see when the next minecart is coming around for example...
Mods arent allowed in most servers nor do purists of the game use them. They are a valuable niche i agree but not meant for vanilla play.
Lastly i dont want to place a banner on everything. They dont go with every build and as i stated, naming a moveable object such as a minecart would help bc u cant place a banner on them.

Portals was just something i wanted. If they break the game for u, u obviously wouldn't have to use them. But i wouldn't ever use a command or a mod. BTW fast travel is available for pretty much every open world game nowadays so having fast travel portals to me as a content creator who is on a schedule, seems worth it.
Appreciate your opinions either way... thanks again.

Kind of confused here. First you can you want to be able and put anything on the map. You can, place a banner on it.

Then second you mention bedrock edition. So this isn't about the Java edition then? For many fans such as myself "Minecraft" is the Java edition. I'm well aware that Mojang changed the names, but if you talk about "Minecraft" then you have to realize that many old fans will assume you're talking about Java whereas other (newer?) players will pick up the Mobile Edition.

Anyway, about the GPS signal: have to disagree with that because it would seriously affect the gameplay. Some options are really best left to mods, such as this. You briefly talk about lag, yet then come up with this idea ;) I think this would be a huge lag drain. And as said: there are plenty of mods which could add this.

Making things not despawn is already possible. If you name an animal with a nametag then it won't despawn. Other block-like entities such as minecarts also fall into this category. I really never had a minecart despawn on me ;)

And then you talk about teleportation portals and that's where I lost interest. That would be such a huge game breaker for me, I really don't think we need that at all.

Not to mention that if you disagree then nothing is stopping you from building them yourself. Make a structure, use a structure block and optionally a command block and you're well on your way. And once again: mods. There are plenty of mods which add a good balanced way to create teleporters, one of my favorites being RFTools.

Some things are really best left to mod builds and not added as a vanilla game mechanic.
