Object Window is a very good feature in sqltpp. However, while working on large databases like Oracle Applications database, we can not effectively use it as the caching itself takes lot of time.
1) So, we might look at the option to allow the user to filter the objects before it loads. I think same or similar feature is there in Toad.
2) Also, we might look at the option of saved filters which is there in PLSQL Developer (Allroundautomations)
