I'm the kind of person who likes to see lots of information at a glance. Wouldn't it be nice to see a summary of all effects for each style on the Image Styles page? Here's a simple patch that does just that.

fietserwinExcuses for the late reaction. I tried this on my test site and it becomes quite crowded. Could you add something like module_filter does with the Modules page (and D8 does by default). Thus a link ("Show effects"?) for each style to open the list of effects? In D8 it is implemented with a details tag, in D7 with a span with class="details".
If you manage to do so, I will commit it.

hargobindWow, this was surprisingly difficult to pull off. There was a lot of complexity with adding the right columns, converting each column to an array so classes could be added, changing the layout of the table via CSS, etc.
I think this satisfies your requirements. There's even a cool feature where the effects will toggle from a comma-separated layout in collapsed state to a line-by-line layout in expanded state. It also plays nicely with other modules that change the columns of the image styles table such as imagestyleflush (which I manage).
