Hi gamemakeru, thanks for playing the game! Here are some answers:
1. We used YEP_SkillCore for the Energy Costs and then edited CGC plugin to customize the skillCostX and skillCostY position. These can be found in line 859 - 860 of IsiahCardGameCombat.js. We are adding this feature in the CGC v1.4.5 update so you will be able to manipulate the coordinates using plugin parameters.
2. The Speed Icons are baked into the Card Base. For each Kaiju, there are three card frames for each speed: Regular, Fast (yellow arrow), Slow (blue arrow), We do want to provide support for custom icons for CGC in the future, but that may not happen for a few versions.
3. This was once again achieved by editing the CGC plugin. The X and Y coordinates for the Card Names can be found in line 856 - 857 of IsiahCardGameCombat.js. We are adding this feature in the CGC v1.4.5 update so you will be able to manipulate the Name coordinates using plugin parameters. The Card Names don't have an alignment yet, but we are hoping to add that in the future.
All of these additions will be made available to all CGC users, including those that support the Patreon :)
