 * BASIC extensions, see the [documentation](doc/Extended-BASIC.md) 
+* extended / tweaked `LOAD` / `VERIFY` commands
+    * start/end addresses are displayed, in the Final cartridge style

+    * command without parameters tries to load first file from drive chosen as above
+* `LIST` command should never damage the screen if trying to list memory content which is not a BASIC program
+* high performance garbage collector
 
 * turbo tape load support (as device 7, or using `←L` / `←M`, optionally with a file name), quite sophisticated: up to 250 blocks (can store bytes under I/O), automatically adjusts for tape speed differences
 * normal tape load error log is limited by free stack space only (no artificial limitation like in original ROMs)
