My apologies in advance if this is already in PDN v4 - I'm still using 3.5 for work and have not had a chance to try it. Currently, all plug-ins' dlls need to be put into Effects folder. That's all good, but after a while, this folder ends up being a mess - full of dlls without having a clean and easy way to know which ones are from which pack. It's very hard and time consuming to remove packs one no longer wants. Etc, etc. Solution: Simply make PDN look not only in Effects folder but in any subfolders there too. That way, one would be able to simply create a folder with arbitrary name, paste all the XYZ pack's dlls there and use them. If that pack is no longer needed or wanted, deleting that folder would cleanly remove it. This would also allow one to organize plug-ins in any way one wants and track what's installed, etc. Many other benefits too. I think this would be one great feature! What do you say? Please feel free to chime in! P.S. Thanks for all the work by the way.
Additional note I forgot to mention originally: this feature would search recursively through subfolders for dlls, i.e. not only first level, but any depth.
