We use SQL Source Control with TFS. It would beneficial if we could tie multiple task IDs to one commit and all changes would in one change set.

ExamDiff pro is an excellent compare tool with merge facilities. See https://www.prestosoft.com/edp_examdiffpro.asp.
It would be great if SQL Source Control also supported this for merging.

A good alternative would be to allow any “external merge tool” to be used for merging, where the application, and arguments can be specified.
The latter option effectively should support almost any merge tool, including WinMerge and UltraCompare

I love Redgate toolkit and SQL Source Control, but would like to integrate it into other tools and processes. Creating a CLI or Powershell (PS) module that allows users to check a database for changes and check in those changes from the command line would be awesome. I am already going to PS to create branches and it would be nice to just check in my change while I'm there.

I would also love to see the ability to manage DB connections for SSMS, VS and VSCode in one location.

Instead of having to address each database separately to link to SOC, why not have an option on the SQL Server instance to right-click and "Link All" databases in one fell swoop.
We plan to implement SQL Source Control and hundreds of databases need to be linked to SOC. We have been directed to some Powershell options which are supposed to link all databases automatically but that option is not working at our installation

From SQL Source Control 7.1.9, the "Migrations" feature has been removed. This is a significant loss. We're told to use SQL Change Automation instead. But that has additional cost - and is only available as the full SQL Toolbelt.
It would make sense to include SQL Change Automation components, but without the continuous integration parts to replace this loss of functionality.

Have the server name of the database (I.E. DEV, TEST, PRODUCTION, etc.) displayed to the right of the database name.

Create a search filter for SQL Source Control, we can have hundreds of objects in our source control, it would be great if you could search by object name and within the objects themselves on a search filter.

supporting SSDT projects with Redgate Source control will allow developers to use the tool of their choice (Redgate or SSDT) when developing database enhancements etc.

"Take theirs" and "Keep mine" are an all or nothing option, I would like to have more control over this and be able to keep my new records but take the updated, or keep my updated records but take the new records, for example.

After linking a DB to Git, I was trying to get back to the Setup Options that are hidden behind the "Setup" tab/button in the top button bar.
The bar was hidden behind the Update banner. As a new user, I didn't even know that bar existed, so I didn't know that I could get there by clicking the "Remind me later" option, until I had opened a ticket with support

With 100s or 1000s of tables it becomes quite tricky to find objects in the static data link / unlink UI. Therefore, I suggest adding a search textbox there as well as making the UI columns (name, key, schema) sortable.

I would like to link a local database in SQL Source Control to our Azure DevOps repository. However, as my Azure login has MFA enabled, I am unable to do so. This is a huge pain and I do not want to use GIT as this is a poor workaround to something that should just work (how long has MFA been around?!).

Please add proper support for Azure DevOps to SQL Source Control, including full support for MFA.

When attempting to get latest changes and an error occurs, please be more detailed (e.g table, data, column, etc.) that caused the error that will allow user to correct the error. It is possible the user getting the latest change was the person responsible for the error, making it difficult to trouble shoot when your database is relatively large.

When displaying the Static Data differences in SQL Source Control it would be very useful to show the number of records that are Different/Identical/In Database Only/In Source Control Only.

When tables have thousands of records it can be difficult to know the scale of what you’re about to check in or get by just scrolling down a long list. A tab displaying the records for each distinct group would be even better.

Currently there is not easy way to see or restore a deleted object that was committed. The object code is still in Source Control - but no easy way to see or restore it using SSMS.

This would allow for the option to move the newer revision pane to be on the left and the older revision on the right.

Add snowflake support

Provide the capability to save the users last sort settings. For example on the Commit tab if I sort by last changed by (asd); the next time I go to the Commit tab it should be sorted by last changed by (asd).
