You may set the application's window to stay on top of other programs, enable transparent mode, minimize it to the tray, if you want to multitask with other programs. The menu has options to enable inserting tabs as spaces, auto indent text, accelerated word navigation, customize the tab, word wrap, long line settings. The application bundles all its options under the Settings menu, which is a tad difficult to get used to. The program supports Regex, and in fact has its own regular expression engine (called Onigmo). You can customize schemes based on the coding language and syntax that you use, and set the default font on a per-scheme basis or globally. Notepad3 has a few color schemes to choose from including a dark theme. Don't like the toolbar, menu bar and status bar? Disable them, or customize the toolbar. Use the View menu to toggle Line numbers, line highlighting, Word Wrap, Lond Line Markers, Indentation guides, wrap symbols, blanks, line endings, Hyberlink and Color Definition hotspots.

Convert text to Uppercase, lowercase, invert case, title case, sentence case, tabify or untabify selection or indent, URL decode/encode, HEX/Char, add timestamps to the text, etc from the various sub-menus in the Edit menu.
