Interesting ideas, however there could be some issues.
Making /fly available in residences would render getting to master /rank useless and would frankly be too op, there is already the free fly goal at /goal and the master rank. Fly is supposed to be difficult to get, that's the point, making it free to people in residences would defeat the purpose and create something quite horrible.
In creative i get the idea, however there is the use of middle clicking a block to get it in your inventory, as well as the creative menu having the search bar at the top so you can find whatever blocks you're after.
The vote roles is interesting, but again we have all the /rewards for people, as well as the top votes per month getting a larger coupon (Top donor gets $15, 2nd getting $10, 3rd getting $7.5) and whoever else reaches the 150 vote mark getting a $5 store coupon, also with the new auto voters it kind of takes the task of voting out of it.
The idea of being able to talk to someone who is muted kind of defeats the purpose of someone being muted in the first place. If someone is muted it is for a reason and as a result they lose the ability to communicate with people, adding this feature would defeat the purpose of this punishment rendering the mute useless which is the opposite of why we mute people.
The colour signs being made free is also interesting, however it is also incentive for people to buy ranks, that's why it is a donor rank perk. However you can get lapis rank for free by voting 150 times a month, getting the $5 store coupon and using that to get the rank if that's any comfort.
Just my personal thoughts on this, hope it helps clear anything upπ
Also everyone can see this! Don't worry π
