Release 1.8 * Added "Arc Dark" theme with blue and orange accented colors. * Added light and dark editor color schemes. Light matches IntelliJ Light and Dark overrides Darcula with many custom color, since originally it was too dark for the panel/editor and text was not clearly visible. * Unified hover effect on buttons and tabs to be lighter and borders on button to better match real Arc theme. * Unified tabs styling, have only hover effect, keep panel color on selected tab (except editor tabs).
