Let me see if I understand this correctly...
Combo Tool
1. select this tool
2. Check or uncheck the options for Blur, Opacity, and Visiblity at the top of the screen. Enter values for Blur and Opacity in the text fields.
3. Click on the screen and key frames are placed for the properties checked and the values in the text boxes applied to Blur and Opacity if checked.
----------------
An optional feature could be using key modifiers instead of check boxes. For example hold down shift to key all 3 properties. Hold down alt+shift to key only blur and opacity.... etc etc.
I think this should be a new tool. I hate modifying existing tools because you run into problems if it doesn't work properly. Plus there is not a ton of space for the tool options at the top of the screen and all those extra thingies would make it crowded.
Yes, I think this could be done. Not saying I will do it anytime soon but will think about it when I get a chance. (trying not to make promises I can't keep.
