The current find and replace features are in dialogs. They kind of block the editor. Please add an option to make them strips(like the qsearch plugin) rather than dialog so they won't interfere with the editor. Or maybe the developer of the qsearch plugin might want to extend it so that it can work as find/replace with incremental search.

I'm not planning to add the replace functionality to QSearch. It would take too much time to implement (believe me, I know what I say after spending months for certain search/find features), while we already have a working Replace dialog and SearchReplace.js script (as well as other scripts).
While not addressing your feature request exactly, the QSearch plugin includes the DialogSwitcher function that allows to switch between the "Find", "Replace",
"Go to line" dialogs and the QSearch panel using corresponding hotkeys.
For example, Ctrl+H in the "Find" dialog or in the QSearch panel changes this dialog to the "Replace" dialog. This helps to turn QSearch into the Replace dialog and vice versa.
If you use the DialogSwitcher function, it is recommended to enable (check) the function's autoload checkbox in the plugins options window.
