Fixed 80x25 text grid editor
Simple Screen Editor is a GUI screen editor designed for fixed 80x25 text-cell environments, with robust width alignment for mixed Korean/English input.
The editing core is implemented in Go, and the desktop shell is built with Wails. It focuses on creating a reproducible text-cell editing foundation, not just a one-off experiment.
The screen is fixed at 80 columns x 25 rows for consistent cell-based editing.
Character-width aware editing keeps cursor position and cell layout stable during insert/delete operations.
Supports OS clipboard copy/paste for practical everyday editing workflows.
Open and save UTF-8 text files, with cross-platform testing support.
It is simple. You only need one executable file. Run it from a terminal as shown below, or just double-click the file.
