+## ExectOS Ideas
+This is a list of ideas that migh but not must be realized.
+
+### XTOSKRNL
+ - [ ] Implement mechanism for detecting CPU features and checking hardware requirements. If CPU does not meet
+       requirements, it should cause a kernel panic before any non-supported instruction is being used.
+ - [ ] Finish framebuffer and terminal implementation. Initialization code is already prepared as well as routines for
+       clearing the screen and drawing single points. Terminal should be instantiable (should be able to create many
+       terminals and switch between them) and work on top of FB. It should define ANSI colors and scrollback buffer.
