Find & Replace for Text Editing

"It does what it says on the tin!" I use it frequently and it does what I need. The fact that it supports regex replacement is a bonus.

Tried this on Clickup + Arc + Macbook. As soon as I put a word into the Find field, it automatically runs the command to replace the text. By default the Replace field is empty so you can imagine the horror of seeing words suddenly disappear without me clicking the button to run the Replace command. I was freaking out if the text was gone. Fortunately I was able to Undo the changes. Never again.

Works well, but is there a way to prevent the widget from closing when I click anywhere in the window? I don’t want to have to open it every time I need to find a word. (I’m using it on a website with editable text boxes, so I have to click on them to open the widget and then get the text replaced.)
