The general idear of some kind of filter wizzards is good, but the current position isn't so good.
Lets say I want to design a new filter for a rect: 1.) I have to open the dialog for the filter effects 2.) I create a filter 'blur1' and add a blur primitive, but the current selected rect does not show any effect. 3.) I create a second filter from a SVG tutorial and call it 'button', but still I can't see any effect. 4.) I have the idea that I could open the fill properties dialog. 5.) I wonder about the blur slider which belongs to no filter. (Does this blur have to do something with filters? If it does, will create a new filter? Will it modify my 'blur1' filter? Will it add a blur to my 'button' filter? Will it modify the blur in my 'button' filter? ...) 6.) I choose the blend mode 'Filter'. 7.) I choose the 'blur1' filter. -> Finally I see the effect. 8.) I wonder why the blend mode is 'Normal' again. 9.) I try to choose the blend mode 'Filter' again, but this doesn't work. So I can't test the filter 'button'.
Suggestions: a.) Remove the blend mode drop down list, and display allways the list with the created filters.
b.) Display additionaly to the created filters a option: 'new custom filter'. This Option will create a new filter effect. Then it assign this new filter effect to the selected object. Afterwards it will open the filter effects dialog.
c.) Add a option to the same list called 'use filter wizzard', which will open a new dialog. It will create also a new empty filter and apply it to the selected object. In this dialog the user can choose a wizzard for the content of the new filter. The wizzard will then guide the user through the progress of filter creation.
d.) Add a option 'import filter', which allow the user to import a filter from other SVG file.

Just came to my mind, it might be useful to place feComposite modes there in the same dialog box with feBlend modes.
Yes, absolutely, and include some useful presets for the "arithmetic" option too (such as "negative" - is this possible?).
And for the actual idea: yes, having a collection of preconfigured filters sounds like a good idea. Then again, things like dropshadow have plenty parameters (place, amount of blur, shadow colour...) It would be nice to be able to fiddle with them when applying a filter.
Yes, but then it will be all adjustable via the dialog, as well as (see my other mail) hopefully the onscreen handles too. And for the blurs, blends, and composites used as parts of some complex presets, you will still be able to use the Fill&Stroke controls. Just make those controls smart so that, instead of just adding e.g. a new blur filter on top of the stack, it will search the stack and adjust the first found blur filter in it, even if it applies e.g. to the drop shadow and not the object itself. (And if the user wants to blur the entire object with a drop shadow filter stack, he can do this just by grouping it and blurring the group.)
