P: Layer effects scripting - 10 bugs - AM code

I worked on script for removing unused effects. Instead I found total chaos. I found 10 bugs and I found that is impossible to do script which will work correctly.

Here is list of sh*ts

1. you can't remove layer style/effect if app.doForcedProgress() dialog is shown
2. you can't remove e.g. second drop-shadow from three even if script listener records code with list item index... it always removes first
3. you can't use code for removing style/single-effect if all effects are disabled or main visibility is disabled. In photoshop you can do it, but recorded code in script listener doesn't works
4. if I clear style with drag and drop fx icon to recycle bin, it removes style and keep blending options... but code recorded in script listener doesn't
5. there is no posibility read options if mask hides effects... so if you read descriptor, change values and set descriptor, it always reset these settings to default values
6. action "paste layer effect and keep advanced blending" is incorectly recorded in script listener
7. if you remove multiple dropshadow effects and last dropshadow remaining you can't remove it with AM code. (It's no longer list of shadows but single shadow.)
8. same situation from point 7 is in case that you want/show hide effect
9. using modified descriptor for removing style has same bug as point 3. ...you just can't set "enabled=false" and "present=false" for all effects
10. show/hide all effects doesn't works whole style visibility is disabled... there are three states of visibility icon. "white - Visible", "grayed - hidden", "invisible - hidden"

And some other bugs I don't remeber now.

I tried to read style descriptor, modify apply
> I can't beacause bugs: 5, 3

I tried to remove effects one by one
> I can't bugs 2
So I did some sorting if there is multiple effects of same kind and layer visibility changes
> Doesn't works - bugs 7,8,3
