Here are some things I would love to see in the product:
1- Being able to see the hidden characters (like spaces and newlines) a grey char like in other apps (I spent quite some time figuring out why it did not work and I had a space at the end which was pretty hard to figure out)
2- Being able to define the app that receives a file from the results (open with...)
3- REALLY NICE TO HAVE - Be able to copy and/or export the list of files in the result list
4- Be able to apply the replacement in just one file in the result list (as a proof of one's regex)
Thanks! Love the product!
