Enhance
In this merger request I have done:
- Rescale redundant blanks at the time axis.
- Rewrite transaction information because the previous one is too long.
- Move the task information (task name and status) from bottom to top of the window. This helped user easier to view task information, especially after a larger number of transaction occurred.
- Next to do: find the best scale for all tasks due to right now there are some tasks are too long ( > 20000 time units) but some tasks just need only 100 or 200 time units and these tasks are displayed together on the same window.
