Thank you for the detailed response. We bought this Asset as well. After using it everything was quickly understood and clear. It is a worthy addition to the "Tool Belt". I personally like having the option to use scripts to manipulate and then having the option on top of everything using ShaderoSprite. Together they are a combined force and make both sides of a team happy which is also a priceless feature.
Thank you for creating these Tools!
Without deleting the unused effects, it's an hard problem to solve, even for us.
Our team are finding solutions to improve this aspect and to provide a new solide version of 2DxFX.
We are actually working on a new major version of 2DxFX and hope it will be release really soon.
