Drag and Drop of Tasks

Hey Team,

What a wonderful product you have created and I have started loving it to the core.

Few points I have experienced while using Quire are:

1. It quite happens that I accidentally drag the task and it becomes child to some other. There is an undo option but for a moment it feels like where did it go ?. Most of the time when I am creating the project I seldom require to move my tasks. So can I suggest to have a switch somewhere which when enabled will lock the drag and drop ? It may be helpful thing.
2. A very minute cosmetic glitch. When the tasks are getting linked to another task, if there is 1 task, it still reads as 1 tasks.
3. Can we have the line icons like (comments exists in this task), the nesting grid line color to be something other than grey so that it is visible.

I will happily update you with my findings if any while using this wonderful software.
