   Rearrange terminal splits on GTKGTKA cross-platform widget toolkit maintained by the GNOME project for building graphical user interfaces in C, with bindings for many languages, giving cyber tools a native desktop UI without writing platform-specific rendering code. by dragging — when a tab has two or more splits, grab the drag handle at the top of any split and drop it onto another split, including in other tabs or windows.
   📍1. Open a GTK Ghostty window with two or more splits. 2. Grab the drag handle that appears at the top of any split. 3. Drag it onto another split (in the same tab, a different tab, or a different window). 4. An overlay shows which side of the target split it will land on; release to drop.

   • Transparently compresses scrollback that isn't visible, reducing physical memory usage by 70–90% for typical text-heavy history; compression runs only while the terminal is idle and decompresses on demand.
   • Raises the default scrollback limit from 10 MB to 50 MB per terminal, made possible by scrollback compression.
   • Adds support for Kitty graphics animation and relative placements, making Ghostty the first non-Kitty terminal to achieve 100% coverage of the published Kitty graphics specification.
   • Introduces a new OpenGL rendering pipeline on Linux and FreeBSD using EGL on its own thread, exporting frames as DMABUFs with triple-buffering, eliminating blurry text under fractional display scaling.
