Search across TaskBots (OR download list of TaskBot blocks)

I want to search across all my TaskBots to find any and all instances of a string (in my case, it's because I have to fix something everywhere). An initial solution could be just to indicate which TaskBots have that string, not necessarily where in the TaskBot that string is.

Added later: An alternative idea that may be more broadly useful is to let us download a list of the blocks in the TaskBot, including the values we've entered into each block's fields. It will be too cumbersome to try to represent the flow with all the paths and arrows, so just a flat list of blocks is fine. Then we can review and search these files using our tool of choice (e.g. Google Sheets, text editor)
