Ahh... back in 0.23... simpler times. I don't document my favorite glitches, but I remember so much.
Unrealistic Areodynamics, no need for fairings, in fact, farings didn't exist.
No 3.75m size.
Pages instead of scrollbars, I preferred pages.
No "Electrical", "Communication", or "Thermal" tab... no need for the latter two, those came in 1.2 and 1.0 respectively, and batteries + panels were with Utility.
No "Coupling" Tab, decouplers bundled with "Structural" and docking ports were in Utility. .23.5's Klaw went into Utility
No contracts or upgrades: speed running was much simpler. Revisit this in Science mode!
Pixellated text
Old skybox
No MH expansion
Old suit
Pretty sure no "warp here" button
And so much more!
Ah, I remember those times.
