Hi, Susannah, your suggestion of providing a Gantt chart view in MLO has been popular. I'd like to discuss some of the factors that could make this into a high-cost low-benefit feature.
If all you were looking for is a task list with horizontal bars
showing start date and due date, that's probably available at a
moderate cost. But I suspect that most if not all of the people
asking for this are actually hoping for much more - I believe that
you will be disappointed with a simple Gantt view unless MLO also
provides project management features such as resource balancing
and dynamic rescheduling.
Let's start with dates. If you follow anything like the GTD methodology for task management, you are not using MLO's Start and Due dates for anything like the date you plan to start and finish the task. Start is the earliest date on which you could start the task, and Due is the date after which the task can no longer be done or is no longer meaningful. For example, if I want to buy tickets to the opera, I might put the date they go on sale as the start and the date of the performance as the Due - If I have not bought them yet on the day after the performance there's no point in doing it now. So maybe they are on sale for three months, that does not mean that the duration of this task is three man-months. Also, you could have a large and complex set of interrelated tasks with complex dependencies, some of which could be running behind schedule, and none of that makes the tickets go on sale any sooner or causes a delay in the performance. MLO is very good at handling dependencies but it does so by managing the active/inactive status of each task. Suppose I am buying the tickets for a group who want to go to the opera together, so I have to put in my order for the tickets, confirm the they are available, then collect money from all of the people, pay for and pick up the tickets, and distribute them. Suppose that takes a month to complete. That means that I really should buy them no later than a month before the performance. MS Project would reschedule the "buy tickets" task to be due a month before the performance. MLO cannot do that because MLO will not reschedule your tasks for you.
In order to handle this simple situation MLO would need four
dates instead of two - you would add Begin and End which would
reflect the plan for when you will actually do this task. MLO
would be free to reset the begin and end dates to reflect your
dependencies.
You would also need to know the actual effort required for each
task, usually measured in hours (different from the Effort field,
which gets a number between 0 and 100, not clear if it's hours,
days or just a relative scale where 100 means "very big"). And you
would need to know how many hours per day you have available to
work on tasks like this. And which days you work and which days
you don't work, like weekends and holidays, including obscure
local holidays. You might need to also track all of the other
things you spend your work hours on, and all of the people who you
will need to help you and their availability. If there are
scheduled resources, like conference rooms or bulldozers you may
need some way of knowing when and whether they are available.
Once MLO can handle all of this, then you need to enter all of this information, and even worse, you have to maintain it - when bad weather or a broken tool or a long phone call from your Mom throw you off schedule you have to remember to update your project plan and see whether the end date changed. That's why most projects that use project management tools effectively have a full time project administrator (different from the project manager) in charge of creating and maintaining project plans and spending little or no time actually working to complete the project. A single person trying to manage tasks on a project management tool usually has an inevitable crisis where you have to choose whether to try as hard as you can to get the project done on time and forget updating the project plan, or spend your time keeping the plan accurate and not actually complete the project.
For your nice to have feature of finding the critical path, a MLO would need further enhancement.
And this brings me to my primary concern. MLO is in my opinion
the absolute top of the line in task management apps with tools
and features that bring power and flexibility seen nowhere else.
If the MLO developers were to invest in all the things described
above, the result would be a passable but primitive project
management tool missing most of the advanced features found in the
many currently available project management apps, like time
tracking to feed payroll, or calculating the cost per value added
ratio for each task to allow outsourcing or elimination of
nonproductive tasks. There would be little reason for anyone
seeking a project management tool to select MLO over the
established project management apps, and not much chance that the
MLO developers could ever recover their investment in these
enhancements.

I'm not concerned with resources, budget, etc.
