Linkshell Limitations

Will there ever be an option to re-order linkshells and have more than 128 players in one? Currently, I have 4 linkshells dedicated to one particular thing with 128 people each. It would be nice if there was not a 128 limit, because FCs can go past 500 members, but linkshells are limited to 128. Also, will there be any changes to being able to see the last time players have logged in a linkshell? It can be difficult to decipher who has logged in recently and it would be nice to be able to remove people from a linkshell when they go inactive and be able to add new people to a linkshell that are active.
