tBar is yet another tool bar capable of displaying your system's status in a compact, well readable form. It features different widgets that can be arranged and colored using a provided configuration file. tBar is written in TCL/TK and is licensed under the terms of the GPL 3.
The OCD pixel-perfectionist in me would like those features..
(i3_workspace) -focuscolor changes the background of workspace selectors, there should be the ability to change the focus foreground/font color as well (to contrast light background colors).
(i3_workspace) ability to change the width of each workspace selector (my font is 5 width, the boxes are 12px, can't center that)
(cpu) -height or similar to make the bar height smaller. (-height does do something, but it doesn't vertically center)
(battery) again made the battery icon smaller, but the character in the battery icon is not centered.
(battery) show minutes left instead of/ in addition to percentage
