I have hundreds of tasks and trying to find a task from that list can be real tough. A lot of times I remember a word reminding me of the task, but it's not the first word so it takes a long while to look for it. Most of the time it can take a mighty long time. If there was a search textbox at the top and I could type in that word, a highlighted text could really make the search so much shorter.
I know there is a keyword search, but a search text box would be more convenient specifically for tasks.
