Additional functionality for the Journal

I am often searching the journal to see if I acquired specific materials and how many of them - both for my own use and also general tracking to see where resources are best found. Would love an option to free-text search. Could be further improved by options to filter for just the searched term, or highlight the search results along with the rest of the listed journal items. Lastly, a way to get a sum of materials or even exp gained during a certain period within the Journal. I have downloaded the csv and done a lot of this in Excel before but its clunkier and more time consuming. Thanks for all your great work :)
