As per Bob's post, it's very helpful for us to have specific, focused suggestions, rather than general ideas like "Improve performance". Having Focus on Speeding up the information window as a separate issue is an excellent example, and with a lot of upvotes, it appears to be a significant issue for a many customers.
If you are affected by this, please post some specific examples on this thread so we can understand what the problem is.
Please include your platform (Windows or Mac), software version, which resource you're displaying information in, what Information Window settings you have turned on/off, your computer speed, and how long it's taking to generate the information.
We'll work through these reports so we can know where to focus optimisation efforts.
