Add an option to validate only modified files #146
Description
Is your feature request related to a problem? Please describe.
Currently, SLDS validation runs across the entire project. This is very helpful for maintaining consistency, especially in large codebases. However, in some cases, focusing only on modified files could enhance the developer experience. When working on a specific set of files, seeing validation results for the entire project in the "Problems" tab can make it harder to concentrate on the changes being actively developed.
Describe the solution you'd like
It would be great to have an optional setting that allows SLDS validation to run only on modified files. This could improve performance in larger projects while keeping the "Problems" tab focused on the files currently being worked on. Some linters and formatters.
