GIMP is really a wonderful image manipulation program. But many of its features are, in fact, unnecessarily complicated. For example,one has to create a new layer before pasting a copied image. GIMP should be able to create a layer automatically for the image pasted and there is no need of letting it remain as a floating selection. And the anchor button, then, should be used as a tool for merging down the layers.
Logo and Text Layer in GIMP should be preserved as vector.And the installed plug-ins should be accessible from a single menu itself.Previews should be available to all the filters. Finally, GIMP should have a workspace of its own.
