I don't know if this has been discussed before...but I'm curious with the actions and commands built into DO if there is room for a regular expression editor feature in the future.
For example...typing *.txt to find all the files with this extension is the familiar way we know how to filter data. But what about being able to use regular expressions to find words in actual files and then showing previews of those files with the words used in the expression?
It seems to me DO designers could make the find filter and find files more powerful by combining them into a central editor that can construct very complex regular expressions for saving and using within DO.
Right now...one could design a button with a single expression to filter out data in certain folders statically. It would be interesting to see if DO can improve this to allow users the ability to create dynamic regular expressions that can be saved and modified when needed within a centralized environment.
