Reply to channel
Do you wish "reply to
I think that hiding conversations into a thread by default encourages conversations in private... so I'd rather have it be the default and then opt out of it manually.
On this group, I placed two features: reply to #channel by default and make reply to #channel sticky (so that whatever you chose, that value is preserved for future messages).
When this feature is selected, the first message you send on a conversation is going to have the "reply to #channel" checkbox checked.
After sending a message on a thread to the channel, this feature keeps the checkbox selected.
