Yes a more general, bundle solution would be fine. I just didn't want to ask for too much, so I asked for a little. This is just an idea for the future. In the future a bundle could include the theme, any theme tweaks, and anything else related to appearance.
I prefer not to have the sidebar disappear too soon as I use a more narrow browser width, and I prefer the sidebar on the right side even with a more narrow browser width. The reason for this is I have multiple browser windows (not just browser tabs) open as I copy and paste data into TW.
The reason I asked for this is I was having trouble adding a new button to the page control bar and I thought it might be because I set the sidebar to be too narrow in my Stylesheet (CSS). But I don't think that is the case now, but for debugging it would be easier to switch back and forth between custom and standard theme tweaks (which define the width of various main elements on the page like sidebar and story river and twiddlers) for debugging.
Thanks!
