Replace Colors
The Replace Colors tool enables you to quickly restyle scripts, it can be accessed by the Tools menu or by right clicking a filter block and clicking Replace Colors.
When the tool is accessed via the right click menu, the current colors for that block are loaded:
By default, all color attributes that exist on the block that Replace Colors was launched from are marked for replacement.
When you click the Replace Colors button, all blocks that have matching color attributes will have their colors replaced with the colors in the New color pickers. For example in the above screenshot if you unticked Replace Background Color, all blocks that have yellow text and a dark green background will have their colors replaced, regardless of their border color.
This enables you to quickly replace colors you don't like. If there's a particular border color you're not fond of for example, just launch Replace Colors for a block with that border color, untick Replace Text and Replace Background, pick a new border color, and click Replace Colors. All instances of that border color will now be replaced throughout the entire script.
