It would be incredibly helpful for enterprise license holders to be able to generate a sort of test license, so that they can set up a test instance with all the features of Enterprise instances (such as LDAP, SAML, etc) so they can test out their settings first before implementing them into their production instance.

We would like a feature to allow leveraging slash command integrations so that users could create custom aliases locally. For instance, one of our integration commands is '/zoom' with additional arguments of 'join' and '<meeting ID>'. We would like to be able to create a custom alias so that a user could always include the arguments along with the slash command without entering 'join' and their 'meeting ID' each time they use the integration.

It would be nice if Mattermost has the possibility to Sync the profile Pictures from LDAP with the JpegPhoto or another custom attribute.

Please make the Data retention and prune/reset/clear feature available on at least E10 we don't need any E20 feature only the data retention.

Some improvements could help administration:

- In the Cluster Status table, highly the node that the user is currently connected to so it's obvious
- Provide a way to connect directly to the server on the local port to debug that specific server.

Any other ideas for improvement?

My organization would like to have the option to not show deactivated users in member lists.

It would be nice if there were a way to reset someone's MFA configuration from the System Console instead of having to use the command line tool. For large teams, MFA devices are lost fairly frequently so it's burdensome to have to use the command line tool each time.

Implement channel management in the admin UI. Currently the only channel administration is in the channel itself or through the CLI.

Make enforce MFA a permission so you can assign it to specific group(s).
Some businesses do want to enforce MFA for some groups and some not.

I think it would be awesome to use Mattermost to host a business domain email instead of Google or Microsoft ect.

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

In addition to specifying custom data retention policy globally across all teams and channels (see https://mattermost.uservoice.com/forums/306457-general/suggestions/10007076-ee-data-retention-and-prune-reset-clear-channel-c), allow

1) team and system admins set custom policies for individual teams
2) channel, team and system admins set custom policies for individual channels

We would like to be able to restore deleted channels. One of which this can be done is to have a trash box of all deleted channels, of which we can restore back to in case we would like to reopen it.

We use MM EE integrate with GitLab EE, so "bots" from GitLab post issues / comments / merge requests to our channels. Today I discovered that MM Search feature does not search (or index?) messages send by such bots as it does not consider them as char participants (from: autocomplete does not offer bots' names, only humans). Is there a setting affecting this or it's by design? Thank you.

It was nice in Slack to say for the batch of invitees that have been recently invited that they be thrown into channels x, y, z instead of having to manually Add Member to varying channels or ask them to seek out channels and add themselves.

When you have a multi user direct message and you add new members (as a conversation grows to need more people) you end up creating a new DM with no history. Instead mattermost should provide an option to keep the history available.

Sample use case: Block .exe files from being uploaded to prevent malicious executables from being downloaded.

In addition to .exe, also interested in blocking PDF files and compressed files.
