## Dump of things that can be improved:
|
|
##
|
|
## - Incoming dialed peer does not change connected state (not relying on it for now)
|
|
## - Unclear if staticnode argument works (can enter manually)
|
|
## - Don't trigger self / double publish own messages
|
|
## - Integrate store protocol (fetch messages in beginning)
|
|
## - Integrate filter protocol (default/option to be light node, connect to filter node)
|
|
## - Test/default to cluster node connection (diff protocol version)
|
|
## - Redirect logs to separate file
|
|
## - Expose basic publish/subscribe etc commands with /syntax
|
|
## - Show part of peerid to know who sent message
|
|
## - Deal with protobuf messages (e.g. other chat protocol, or encrypted)
