Hi Smartsheet!
I have used Smartsheet at my former job and have now recently switched job and am evaluating what PM tool to use within the new company. The overall experience from working with Smartsheet has been positive but the tool however has one very critical shortcoming as I see it (at least for how we wanted to use the tool). Let me give an example:
Let's say I create a task that will take 10 days. Now, during that period I might have another task that requires only 1 day of work. The only way that Smartsheet allows me to plan this is by splitting the 10-day task into two tasks and placing them with a one day gap inbetween them. Then I'd place the 1-day task in that gap. This way the resource will not get overallocated in the system.
This in itself is very inefficient way of having to plan things and it creates a lot of "duplicate tasks" in the time line. It becomes even worse if I have to replan this part of the time line. Let's say I for example need to add another small task within this same time period, then I might need to create another duplicate task out of the (initially) 10-day task. Also if things happen that makes me have to shuffle things around a bit (maybe the 1-day task can't be moved in time but the 10-day task need to start a bit later) then I have quite a mess to handle with all the duplicate tasks and "uneccessary" rows.
Now, this problem gave us such a headache at my former company that I am now worried about bringing Smartsheets into my new company. If I knew that this problem was being addressed and that there is something officially in your roadmap that would counter these problems then I would go for implementing Smartsheet without hesitation 
So, my question basically is; Do you have this problem on the radar and if so, when can we expect a solution for this?
Cheers,
Fredrik
