v4.0 12.01.2020 Replaced GM_addStyle (deprecated in Greasemonkey 4.0). (Thanks to Tehhund for reporting the issue.) Also added @updateURL and @downloadURL for auto update support. Tampermonkey should still work with version 3.1 of this userscript, so if you use Tampermonkey, you don't have to update unless you want automatic updates.
v3.1 22.08.2016 Version 3.1: 2016-08-21 - (Minor syntax cleanup...version 3.0 still works for me.) Added "Modern" to @name to distinguish it from Rhomboid's original script. Removed extra ";" in "box-shadow" line and some extra spaces.
v3.0 01.01.2015 Version 3.0: 2014-12-31 - Updated version 2.0 of Rhomboid's script to add compatibility for Modern theme (got narwhal showing again for Preview button, added text wrap within Post button, stopped background image from changing position on hover); general style enhancements for buttons (added glow effect for better text legibility, highlighted border on hover). Should also still work with the Classic and Plain themes. Note: Laser kitty untested.
