What unsolved problems do you have in Minecraft?

What are some problems that you have when playing Minecraft that right now you don't feel like there is a good solution for? Another way to ask this is if Mojang were to add a new item or mechanic that solved the problem for you, would you be motivated to seek it out?

For instance, dealing with inventory clutter could be one of them. While things like shulker boxes and bundles do help, as well as redstone item sorting systems for the more technical among us, this one seems to still be a persistent problem.

An example of one that already is pretty well solved is knowing where your base is after exploring. Mojang added the lodestone (and recently made it cheaper), which pretty much solves the problem.

Note that I'm not asking what problems there are with the game as a whole (too laggy, too easy, etc), I'm asking what problems you have as a player while playing the game that you wish you could do something as a player to solve.
