Is it good to have a text tool bar for the throwaway filter texts?

Thanks for the handy tool, it helped me a lot!
Besides the most useful filters which can be saved as .tat files, there are some throwaway filter texts which may only be helpful for the current log file. I feel it is helpful to have a quick filter for those throwaway filter texts.
My thought is to add a textbox control at the right of the menus. Then the user can input any regexp string, and then the tool shows the filtered lines in real time.
Right now we have to add a new filter, input the conditions then click ok to close "Add Filter" window, then check the results.
Is it a good idea?

Here is an example:

I'm not sure how much easier this is versus the current steps: Ctrl+N, type filter, hit Return. The only difference is clicking with the mouse vs. typing Ctrl+N. Am I missing something?

Thanks for Ctrl+N, I didn't pay attention to it before.
hmm...There is one major difference: For the new enhancement, the filtered result will be updated in real time when the user types so he may modify the filter text repeatedly. Ctrl+N almost assumes the user already knows his filter text.
