There is a flush of new software versions at the moment and the most recent is MindSystems Amode. The tool promises to combine visual planning, information handling and project management into one application.
I've been using the trial system for some days now. For a quick start I took advantage of Amode's import function and brought in an MS Project plan. This was smooth and quick and brought in all the detail.

Amode presents the project information through many different views and panels. It lets you slice and dice a a project into many sub-projects - this is great for keeping track of things in streams or stages.
Using the Briefcase feature you can create several "stacks" of these sub-projects so that you scan across more than one at a time. Next to be explored was personal task management.
Again, for a quick start, I imported a MindManager 8 map that holds some of my current to-dos. As before, the import was easy, quick and complete. My to-dos are presented in a tree structure - the main branches of each tree being the main topics from my MM map. Here I'm able to set and update task/time data, view notes, link to files and web pages, manage relationships and more.
I updated the status of several tasks to "complete" and then viewed these using the filter function. I like to keep my completed tasks for a few weeks but don't like them cluttering up the "active" task list. Amode allows me to create a separate project for the "done" items whilst retaining these within the overall file [Amode calls a collection of projects held in a single file a "solution"].
This maintains a nice separation between completed and active tasks. I'm now thinking that I'll create a new sub-project for done items each week, which should help weekly reporting and give me an audit trail or sorts. If I want to view several "done" projects at once or compare them with the active project(s) I can do this through the Briefcase mode.
There is also a Gantt view where I cans see the tasks scheduled over time and also a Calendar view, much as for Outlook. Indeed I could export the tasks to MS Outlook if I so wished however Amode has a task alarm feature that may mean I miss out the Outlook part of my personal management system in future. I can of course also export to MS Project or MindManager as well as Word, Excel and Open Office Writer or Calc.
I am impressed with the way MindSystems Amode brings together lots of information created in different project management tools. I think it's going to be a powerful tool for anyone managing projects and tasks. See more at the MindSystems web site or download a free 21-day trial.
