Couple of thoughts...
I've just started using this product and really like it. I have the following initial thoughts:
Allow for drag and drop of sub-tasks to move them under other tasks or to change their level in the hierarchy.
Allow those of us who do not want to use the progression tracking features of this program to turn them off. They just get in the way. Same goes for Prerequesites / Dependencies.
When entering dates (i.e., Due Dates) allow for entering just a date and not a time.
Allow for tasks to be treated as all day tasks and display them clearly in the Calendar view. I have multiple tasks to do on one day and the Calendar view lumps them all together without showing what the tasks are. Also, when displaying a task in Calendar view, show the text from the parent task so the task is more easily understandable just by looking at it's description.
When entering a new Task / Sub-Task, add a Cancel button so we can just Cancel if we want to instead of having to Save a blank task and manually deleting it.
In Calendar view,
Please make separate feature requests for distinct ideas. Otherwise, how will people reasonably vote to support your suggestions?
Re: these,
1. This is already the case. Drop any task on another and it becomes a subtask to it. Drag it to the bottom of the screen where there is no other task and it will move to the highest level (you may need to filter or search so that there is some white space). You can alternatively use copy and paste or “paste as subitem” commands. Basically this is complete.
2. This is already requested. Please vote for it here: http://taskcoach.uservoice.com/forums/26465-desktop-version-windows-linux-mac-of-task-coach/suggestions/472334-make-task-progress-a-selectable-feature-to-turn-of
3. This is also already requested. See here (and notice that already if you use “end of day” and “beginning of day” in the preferences for the proposed times, it hides times so you can ignore time):

4. this could be a separate request posting, but note that there are many overall ways the calendar could be improved. We’re aware of that. If you post this separately, please make it very clear how you want this to work
5. I like this but, note though that you do NOT have to manually delete, you can close the window and press UNDO.
6. this is incomplete, I don’t know what your request was.
