Hello,

it seems https://github.com/AlphaNodes/redmine_messenger/pull/105 this is not accepted. Are there any outstanding issues?

I have planned a few other changes:

• add a toggle for Inherit configuration from the parent project
• add ability to add multiple integrations per project - e.g. features are sent to one mattermost channel, bugs to another mattermost channel

Would you be interested in those?
