I would like to see all recent posts in one page.
Think of it as your personal conversation timeline.

Where lots of users join, I find it interferes with seeing real content. Any screen is dominated by System join messages.

We'd like to edit each others posts, e.g., for meeting reports and the like. Before, we used Slack, and found this feature really useful.

Right now the scope of the search feature is limited to the current team. It would be great to have option allowing to specify the scope: channel, team, global (for example)

We use the favorite channels and direct messages, and therefore would like to collapse the public channels. Then channels with unread messages would only be shown.

Would be nice to have the ability to update/modify a user via the CLI. Similarly to create user, you are able to set their name, email, etc. It would be nice to be able modify those details of an existing user via the CLI or even UI. I've found some user's end up entering their names all lower case or some don't even enter their details.

Hi, (I am new to this forum but I have installed Mattermost in my organization)

Is it possible to add a new choice in the administrative console in the option “Allow users to open private message channels with” to request permission to create private messages with members who use the platform.

Currently, the configuration choices are:

All members of the team
Any user on the Mattermost server
and I would like to add :

Only authorized members
To prevent all members from communicating privately without prior notice

Is it a good idea ?

Securing your chat server should not depend on the size of your wallet. I think there are enough other reasons for enterprises to pay for Mattermost (support plans, branding, LDAP). Allowing additional security to private persons, open source- and small teams would be awesome.

Using various colors for nicknames improves readibility a lot!

Slack does it already.

In some cases we need to delete all private conversations from an old user but without deleting the user (so it doesn't break continuity in public conversations).
We use an SQL query:
SELECT DISTINCT Name FROM Channels INNER JOIN
(SELECT Id FROM `Users` WHERE `Username` LIKE 'Foo')
sub ON Name LIKE concat('%', sub.Id, '%');
Then "platform channel delete" to delete the channels.

But it would be much easier to have a CLI command that does this.

Pasting a multi-paragraph block of text for quoting is currently frustrating, as you can't just type "> " and then paste and hit return, because if "\n\n" happens to exist in the block, it'll fall out of quote mode.

Since we already have /code for code pastes (like HipChat), let's also go for /quote: you do "/quote <paste><enter>" and done.

The implementation would be virtually identical to /code, just replace the 4 spaces with "> "

Provide the ability to conduct user polls within the channel

I know these features were left out of Team Edition to keep it simple, but these options are present in the config.json file.

Enabling this features from just the config.json file would keep the team edition ui simple, but give smaller teams the same ability to control the whims of their users

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.

With MM 4.1, emojis changed their skin tone to a yellow one, to be neutral. But yellow is ugly and if you agree click on that great button

Support avatar icons for channels.

it would be great if the service and apps provided a similar API and UX to allow profile images to be assigned and queried for a channel.
This might work similarly to what is in place for users, where the Mattermost API supports getting a profile image for a user, except this request would provide profile image by channel.

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.

Show a member list on the side of the chat window listing all the users that are in the current room, sorted by status and then name (so that logged out users are at the bottom).

This seems critical to communication .. who's in the room, who's online, who am I talking to, am I in the right room before typing @everyone, etc. At a glance. The little member button with drop down is insufficient especially in rooms with hundreds of people.

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?
