The system console shows the SMTP server password in clear. No other application/website with sane defaults does that. Some offer a button next to the password field to reveal the password temporarily, so the user can make sure no one is standing next to them who could see the secret.

I actually consider this a bug, but it was rejected as such: https://github.com/mattermost/mattermost-server/issues/10909

I tried to implement a plugin which supports spoilers and moderated posts.

To achieve his would require me to process or format the post when it is being rendered.

Support importing of private channels and private messages as these are part of the slack compliance exports.

It would be nice if "in:" could support direct messages. This was discussed in

https://github.com/mattermost/mattermost-server/issues/7762

which depended on https://github.com/mattermost/mattermost-webapp/pull/189 which was already merged, so maybe this isn't too hard to add now?

Currently I can't create messages with more than 4000 characters. This limit should be removed.

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]

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.

... instead of having to click "Load more messages" over and over.

*useful for keeping to-do lists, and reminders

Enable the functionality to allow users to easily share images directly from other applications (such as the gallery) to a channel Mattermos. I am a developer of mobile applications and have some experience with Android, I would like to implement this functionality

https://developer.android.com/intl/es/training/sharing/receive.html

We are using HAProxy and multiple subdirectories as internal redirects, to consolidate services.

Right now, Mattermost assumes it is being install at the root of a fully qualified domain name, so moving it anywhere breaks multiple paths for many files.

It would be much more valuable for teams to be able to deploy to "http://www.example.com/chat" instead of always resorting to "http://chat.example.com/".

Current iOS and Android (i heard) are hybrid apps (web app encapsulated to native app by something like Cordova) what means UI is not perfectly integrated with OS what means at least worse UX.

Do you plan to make app with really native UI (native in Cocoa or React Native)?

All member by default after invited, can create channel, private groups etc.. how to stop this? Only admin should be able to create channels and private groups..

It would be great if mattermost allows to export all of user data(users, channels, message, ...).

I think it is important to persuade my coworkers to start to use mattermost.

Slack provides tighter integration for bots like hubot and calls it Bot Users. Slack's documentation describes it in depth: https://api.slack.com/bot-users

For example, one of the most import advantages is talking to the bot in a private manner (direct message).

It would be great if Mattermost provided this.

For compliance, add the ability to delete specific messaging entries from the user interface, including:

- Clear a specific channel of all its content
- Delete all posts from a specific user
- Delete all posts from a specific user in a specific channel
- Delete all posts from/before/after a specific date
- Configure a data retention time

The notification emails are HTML only, which is a pain when you read your mails in plain-text mode (or if you use, say, mutt).

The mails should be multipart : a plain-text version and a HTML one.
