[Laplacian pyramid filter effect plugin]

I just added this effect but i can't find it in PDN v3.5.11. Is there a requirement to use 4.x now? I haven't updated because I don't want to lose a bunch of plugins. Thank you for any help you can provide.

[All effects disabled after 4.X update]

The latest update (4.0.x) disables all of my effects. Going back to 3.5.11 brings them back. Is there a trick to getting them to work with 4.0.x?

[Feature request: crop to specific size]

In photo shop, you can crop a picture to a specific size. I would like to be able to do the same in paint.net. This program loads faster and is fast becoming my go to program. Thanks.

Example: I have a picture that is 3200 x 2500 and I want to crop the dimensions to 1680 x 1050 (I know I can change the picture size or canvas size, that's not what I'm talking about) A lot of times the pictures that I get aren't the same aspect ratio as what I want and I need to see what I'm cropping out of the picture.

[Plug-in request]

I would like to see a plug-in that works like PS's crop tool. You can specify what size the resultant picture will be. eg. 256 height X 256 width.
