Pardon my ignorance, what is wrong with leetcode (aside from the name)?

A few features I would love to see:

1. A way to view groups of multiple communities in a single feed. Like a multicommunity. A workaround right now is to have multiple accounts, which is less than ideal.

2. A way to view content from multiple accounts in a single feed. Like a universal feed.

3. An easier way to have the same settings apply to multiple accounts.

4. A way to block instances or communities.
