The same way we can send messages, we should be able to send voice messages.

It should be as simple as click "add voice", record what you want, press send and it's made available on the server for others to listen.

It should be supported by browser and mobile client apps.

for the default search backend (sql), search results are capped at 100!

you can verify this by loading jquery and doing:

$('.search-item__container').length;

you can see that paging isn't supported:

https://github.com/mattermost/mattermost-server/blob/master/app/post.go#L821

and the sql uses `LIMIT 100`:

https://github.com/mattermost/mattermost-server/blob/master/store/sqlstore/post_store.go#L834

i know this isn't an issue in enterprise because you're using elasticsearch, but please either bring elasticsearch to team edition or fix the default search backend. 100 results is sad :(

A user should be able to easily see & search the list of all channels they have joined and can join. I'm seeing a number of duplicate channels created across teams because the user did not know it existed in another location.

If a user misses replying to a thread in a channel and instead replies directly to the channel, this message is not part of the thread that it was intended to be and the conversation is not clear.

There should be a way for a user or channel admin to move a message to the intended thread inside the channel and keep it inline with the on-going threaded conversation (since everything is timestamped this seems possible).

This would clean up the conversations and mistakes that users will make.

A toggle option so that threads appear as "N comments" and open in the side-panel, so they do not interrupt the main flow of the channel, and you can follow each thread mode easily.

Just like we have tumbnails on pictures. helping us identify what we are looking for without having to open the preview tool.
It would be great if we could have thumbnails on videos too.

When users have their mattermost window open all the time, animated emoji that are endlessly looping can be very distracting and annoying. If they paused after looping a set number of times, it would greatly improve the user experience for me.

In some channels some messages are ‘must read’...
An option ‘I have read this one’ would be great then.
It would also be nice to be able to reorder the pinned posts.

The installation should be only depending on a ftp-access to a hosted server storing data in flat files. Second best would be mysql connection.

Team admin can edit users messages (when option is available) but it can be usefull to specify when it's not the user himself that edit, but an admin.

Proposal: add "(edited by admin)" instead of "(edited")

Admins can enable/disable join/leave messages in config console

Users seem to expect that "Flag post" means "Report post" and do not think of it as a way to bookmark posts.

Especially as in the web-app "flag post" is not displayed along the other post-actions, but instead by the side of the posting username.

I already filed that as a github issue: https://github.com/mattermost/mattermost-server/issues/9990

In cases of a international team managing time zone is often difficult. It would be great if Mattermost supported some kind of timezone conversion. A user can choose his timezone in settings and when posting dates or times in a chat, a special syntax, probably something along the lines of (12:00 PM) would be required. The clients will auto convert the time to local users timezone while displaying. This could be an opt-in feature.

Galera cluster provides multi master SQL database (e.g. upon MariaDB or MySQL) and can help strengthen the database backend. As it easy to deal with mattermost-server outages (simply run another instance very quickly), it is mostly painfull to deal with single DB outage.

Galera cluster can be supported in a direct way - add all db nodes to the configuration and use it in balanced way or as a fallback - or can be used via haproxy or similar.

Make Mattermost API channels search method
( /teams/{team_id}/channels/search )
to include private channels where the current user is a member.

E.g. if the user A is a member of channel B and user A performs channel search, it will get channel B in a response from server if B matches the term.

In Mattermost 5.5.0 search returns only public channels in results. The only way to find channel by display name is to get all channels current user is a member of and iterate over them on client side.

Add the possibility to set a "default" team for every user. Currently the teams i am a member of are sorted alphabetically. If I login via GitLab the first team is selected.
I would like to have the option to select a "default" team which is automatically selected after login and not the first in an alphabetically order.
