Make each project remember how I had timelines and windows arranged so it opens EXACTLY as it was when I last used that project. I arrange things differently with some projects and saving a workspace DOES NOT keep my timeline windows arranged in order nor remember that multiple timeline windows were open. I often leave small pre-comps in the default location under the Composition window and open a separate Timeline window for large comps in a second monitor so I can open things up and see all the layers. These setups are NEVER remembered and it gets annoying to re-order things every time I start up an existing project that gets regularly updated.
