Tine is a simple text/code editor initially designed as a main work tool just for me, so I did only things I needed, but after some time it turned out it might be useful and helpful for others.
The main goal of this editor is to keep the focus on the text editing and not be distracted too much by buttons, tabs, menus, and animations. So there is almost no UI. Text navigation and the editor interactions are strictly designed for keyboard use (since I hate moving my hand during typing and using the mouse); however, some basic mouse support was added after some time (mostly for cases like a quick presentation of code to colleagues and similar things).
I mostly use C/C++ at work so the editor is designed to be used with those languages.
I used Emacs a lot so my Control key is remapped to Caps Lock. I think such Control key position is way better and ergonomic, so consider do the same. Default Tine keybinding is a lot about pressing Control. Also right hand touch-type home position is used as a base for the cursor movement (arrows can be used too).
My default working OS is Windows, so the editor was designed according to it. However, porting to other platforms might be possible since the language API used for the editor supports also Linux and Mac. I just didn't spend too much time implementing features like hot-load and process execution there.
