When you want to edit a solution you have to select a project and only from within this project you are able to edit the solution and publish it.

When you come back to the main page of LCS and you select the solution tile, you will see that the solution is opened for Edit but you do not see in which project.

As an ISV we have more than 50 LCS projects and when you do not know anymore in which project the solution is set into edit mode you have to go through all 50 project to try which it was.

Solution: add a column to the grid so you can see in which project is has set into edit mode.
