I wish i had the knowledge to develop my own extensions but unfortunatly i dont, and i know its a time consuming task. I dont wantt to come accross demanding just giving ideas. Some know doubt have been mentioned before.
What i find is there alot of "similer" extensions, and others that do things that can be achived without the extension but does help, but i wish there were new upcoming extensions that allowed things that as far as i know MMF has NO way of doing and is therefore starting to lack behind a bit.
Extensions i wish were available.
Scanner / Twain extension.
CD/DVD writing extension. (cant belive this has never been done)
USB communication extension. (for custom USB devices like serial object)
Better windows objects like panels, group boxes, frames, toolbars etc that are "OS current", so smooth, resizable ETC.
There are more but these are off the top of my head.
Any developers want a new project, heres some ideas.
