Slack has that features (Preview/Shuffle/Cancel) before posting and it's GREAT!  It's annoying to post a Giphy and then see that the picture chosen by the system is not nice or funny or whatever you were expecting.

Yes...reminders can be used to bookmark items, but it requires several actions:

1. Click on the dropdown menu of messages to open it up

2. Click on Set reminder.

3. If you don't like the default time period to remind you, TYPE the quantity of time.

4. If the above is true, you might need to change the time period (minutes, hours, days, etc)

5. Click SAVE.

The Bookmark or Star button should be placed next to the Reply or Add Reaction buttons.  Bookmarks should appear in some special section, in the order they were bookmarked (most recent first).

Regarding Tasks, what do I want as a user?

1. The ability to create a task from WHEREVER I WANT and assign it to WHOMEVER I WANT. 
2. The Ryver team should NOT make decisions about what users like.  If a I want to assign a task to a particular person ONLY.  Why not let me?  I should be the one to decide when I want to assign a task to a team and when to a person.  
3. The ability to write a task command from ANYWHERE in Ryver.  Right now you can do that only from CHAT, and not from TASKS or TOPICS.  There should be a command line also below CHAT and TASKS.
4. The ability to QUICKLY create a task with a command, and have it populate the task with the most important information.  Right now to create a Task with a due date/time and assigned to somebody, in Busybot takes me only one command and one click.  To create the same task in Ryver takes me: 1) Write the /task command, 2) Write the Subject, 3) Click on Team if I want to assign it to somebody, 4) Search for the Team I want to use, 5) Search for the teammates I want to assign to, 6) Click on Set the Due Date, 7) Pick a due date (I can’t pick date and time when first picking, only date), 8) Write the Due Time, 9) Click on Save.  In summary, 2 actions on BusyBot, 9 actions on Ryver.  I hope you can see the BIG DIFFERENCE it makes for us users.
5. Besides the fact that I could want or like to assign something to a specific user, what about when I NEED to assign something to a specific user and it is supposed to be PRIVATE?  Why should other people be aware of such a task?  In Ryver, I would need to create a special Team of 2 people, me and that user.  Seems ridiculous.

Somedoby from Support at Ryver told me: “The biggest risk of introducing this feature (assign privately to one user only) is it would be really easy to just think in terms of "who" you want to perform a task, and always create tasks directly for them.”  

In MOST cases, I don’t mind and I even want a Task to be assigned to a person under a team.  So, why not make it the DEFAULT?  In other words, say I need to assign a task to a person in our Website Catalog team.  Once I assign a task to that person under that team, the default team for that person could be the last one used.  So, if for example I create a task using /task @user1 @team3 TODOSOMETHING Tomorrow 11 am, from then on I would not need to add the @team because the system would always use @team3 as default, until I change it.  Even better… the first time I create a task and assign it to somebody, FORCE ME to pick a team or make it private.  And use that as a default for the future.

I understand Ryver wants to foster collaboration.  But in doing so you are forcing users to take many mini-actions (click, write, click, click, write, click, write, click, click, etc).  It’s OK if you do this once or twice but it’s very annoying and time consuming for somebody that creates many tasks during the day, like many managers do.

I would also add that Ryver has to give Users the ability to write a task command from ANYWHERE in Ryver.  Right now you can do that only from CHAT, and not from TASKS or TOPICS.  There should be a way to write commands EVERYWHERE.

Bookmarking seems similar to what Slack does with the STARS.   It's one of the main features I like and use on Slack.  Many times I can't answer something immediately, or even if I answer it I want to review it later.  I know that I could create a Task on Ryver, but it's much easier to Bookmark/Star it with one click for later review.
