1) Custom window title.
2) Temporary download folder.
1) I did some research and experimenting and I can change the window title to what I want. The question then becomes do I want to do it? If so, what options do I provide and how to I configure that? A special problem is language support. I noticed that the sidebar title does not follow the window title (the tab does). I'll probably fix the sidebar even if I don't implement this request.
2) I suppose this could be done. I don't personally have many interrupted downloads and don't see the problem. A request from someone else was to add the ability to move files to other directories after they are downloaded, not automatically like you want, but on user request. They want to always download to a temporary directory and either delete the file or move it to a permanent directory, after they've had a chance to check it out. That sounds like something I would use myself and I'll probably implement it someday. Maybe that would be enough to satisfy you as well. If not I'll keep it on the list for some future date, but only after I do the move on request.
I am looking at the "Clear List" leaving info at the top instead of clearing it bug. It's not the simple fix I was hoping for, but I will take a harder look at it eventually.
I am slowly working on 0.9.3. Most of my time to this point has been to work even better with themes. I have ten of the top themes to test with and now work pretty well with all of them, except maybe the Walnut theme. I can now change the buttons in the download list to be text or icon, just like the buttons in the toolbar. That way you can use those buttons, even if you hate my icons.
