Strikethrough / Hide completed tasks

[Dymium]

Maybe it's just a silly question, but is it possible to hide or strikethrough completed tasks in the Data Explorer?
Now it's just a shade of grey, and to me with my color blindness it's not so clear for me on LCD/TFT screens..

Since I don't want to deleted the tasks that are in Projects, sometimes I write some comments/hints/tips in tasks which I want to be able to search. Because and I want to be able to review on how I did some things.

Therefor it would be nice to be able to hide/strikethrough completed tasks, espacially to be able to hide/unhide completed tasks.

It would give a cleaner view to/of uncompleted the tasks in a project. I've tried making the flags visible but it only makes the screen more crowdy.
