Yes. This is why I work on this project. But my first proposals was not make editor for large text. I actually not think about it at all. My main idea is make clean and extendible text editor. So anybody can understand how layout built, where text insertion happens, how it processed, how cursor wors and etc. I want text editor which is not required hacks to simple tasks like allow only numbers, hide cursor, disable text selection, make masked input, make smart completions and etc. > Stef > > > On Apr 27, 2013, at 5:17 PM, Denis Kudriashov <dionisi...@gmail.com> > wrote: > > > I should say it is not difficult to do with current design.
