We have several teams at work and each channel in the team has a specific purpose. It would be ideal if we could set a time at which a recurring message of the day would be posted. We would include links to resources for the team as well as recent news for people who have been out of the office and are returning.

It would be like an extension to the header and purpose sections. Ideally tagging people would work such that some of the messages can act as daily reminders to everyone of the schedule.

The RTM API allows integrations to connect to slack from behind a firewall, seemingly connecting much like a normal desktop client might, from any computer, not just an externally visible server.

It's a very important enterprise feature for those wanting to integrate Mattermost with their internal applications.

Further discussion on this can be found here:
https://forum.mattermost.org/t/does-mattermost-support-real-time-messaging-api-from-slack/1287/2

And this slack FAQ describes the differences between the Events and RTM API's:

This is the Slack RTM API spec:

Notifications are challenging, and a common source of friction seems to be "hey, you triggered a notification I didn't want by saying @all".

Slack handles this nicely: they intercept the message before send, and advise the user of the outcome.

> By using @all, you are about to notify 123 people in 12 timezones. Are you sure? [edit message] [send now]

Right now you can only navigate through images posted at the same time, whereas slack will let you navigate through the entire history of images

Mattermost fetches images from a URL to that image, however it ignores the exif data. This results in the preview often being in the wrong orientation.

Bots are only able to post text messages to rooms, however, it would be convenient if bots were able to attach photos as a message to the room.

We would prefer if our bot didn't have to upload images to an accessible URL and then post that url to the room (and then only get a preview of an image), as this adds a few extra steps to viewing the image and requires our bot to be aware of when it is done uploading the image to the host and then finally post the link to the room.

It would be nice to have an option, that enables the user to hide contacts that are currently offline.
This would mainly apply to the "direct messages".
It is really annoying to search through a long list (~50) of contacts you often need to chat with, when about 50% are currently offline and are therefore of no interest at the moment.

At present we can render tables, can we have the control to left/right align the tables.
Use case : For me my data is some what large, which can't fit in a screen. If we have the option to right align some tables, i can manage the space.

A companies security policy often has rules stating that a password may not be reused. To facilitate this many applications have a feature that allows the administrator to state how many passwords the application should remember until a password can be reused. Think, for example, a maximum of 10 password that the application must remember.

I got asked by a colleague if it is possible to sort the Users because he had about 60+ Users in the Direct Messages section.

It would be nice if you can sort it by a specified department (or Position) or that you can create User groups (with specific permissions for example) and that they get sorted in categories like this.

An other way could be that everyone can create custom folders with users in it and can expand it if needed.

Currently, we have users that work in close proximity to one another, and sometimes take on each other's identities, it would be nice if we had a way for a user to delete their direct message history. Reopening a direct message with a user should start fresh. If the logs remained unchanged that would be great too.

I'd like to somehow tune the color scheme of the Mattermost to separate private chats from channels. First idea that I got my mind is that maybe there could be an option to set a different background color for private conversations?

On Slack, Bots can interact with users by adding UX elements within the message as you can see there : https://api.slack.com/docs/message-buttons

This would be an awesome feature to have in Mattermost.

Some Mattermost instances have many channels and a crazy number of posts, leading to searches on terms returning too many results. It would be good to be able to search by date range. For example, gmail uses after:yyyy-mm-dd before:yyyy-mm-dd and probably other date formats to enable searching by date.

Would it be possible to add custom selection of username, nickname and full name to teammate name display? This would make it possible to use combinations like John Doe (Johnny-boy) or John Doe (johnd).

How about adding touchbar integration for the latest Macbook Pros? This is one thing that HipChat had that was quite useful - could be used for emoji search, setting away/dnd status, etc.

Thoughts?

User icons are okay now on the left side list but would it be even more clear to switch the icon color to white and change the background color for the status? Please check the link for a demo:
