Superfast editor even with many lines

It starts to get slow after 1m lines!!
Also decorated the search and replace dialog.

!!Windows Users!!
A friend of mine downloaded it in front of me and Windows Smartscreen was complaining. (I am sure you have your reasons to be on this platform and you trust that windows keep you safe and secure from malware but) do not worry I have not included any weird deletion scripts or ANY analytics trackers/geolocation services/ads like many others have!!

Enjoy!
