 ### New Features
 - Added Coulombic efficiency (`ce`) as a parameter option ([#4](https://github.com/NREL/thevenin/pull/4))
 
 ### Optimizations
 
 ### Bug Fixes
+- `Solution.plot` now blocks at the end of a program ([#5](https://github.com/NREL/thevenin/pull/5)). Figures no longer automatically close when programs are run from scripts. Blocking only occurs at the end of a program so that opening figures do not stop other lines of code from running.
 
 ### Breaking Changes
 - New Coulombic efficiency option means users will need to update old `params` inputs to also include `ce`
