Hello all! I've recently started using Galaxy, and it's a fantastic piece of software. However, I had a question about a possible feature, and any suggestions on how to implement it. My use case involves working with a lot of histories, and I need to jump back and forth between them fairly frequently. However, it's a bit inconvenient to have to click on the "Options" button on the rightmost pane, "Saved Histories" in the drop-down menu, and select my history on the main pane. An easier way to switch between histories that were recently used could definitely benefit me, and perhaps other people too. I propose an easily accessible list with links to the 5 most recently visited histories. I took a look at the source, but as I'm unfamiliar with Django and the Galaxy codebase, I thought it might be best to come here for advice. My initial thought was to show the last 5 most recently updated histories underneath the "History Lists" in the options menu. However, that would probably cause trouble when working when Shared Histories that other people are working on, jumping up to the top of the list whenever anyone edits them. The best solution I could think of was to have some sort of list of the histories visited. When the user selects a history, that history is pushed to the top of the stack, and if there are more than 5 items in the stack, the least recent history is popped off. Ideally, the user wouldn't need to go back to the "Saved Histories" or "Histories Shared With Me" grid when working with a few different histories at once. I'm also not sure where the user's state is stored, so I don't know where I would put this variable. I'm also not sure if there's any hooks or anything when selecting a history that I could take advantage of to push it to the top of the user's stack. An issue with this approach is that an item from a history may be open on the main pane, and the user can select another history without going to either grid of histories. This problem doesn't currently occur, because the only way to select a different history is by opening up the history list on the main screen. The main pane needs to be changed to something else upon changing histories, but I don't have any ideas as to what would be best. Perhaps the default "Analyze Data" screen? Sorry for so many questions! Any answers or suggestions would be much appreciated :) I'm also curious if anyone would benefit from this feature besides myself!
