Worked on the topmonks/hlidac-shopu repository to align the extension’s monitoring scope with current business priorities by removing discontinued shops from both the homepage and About page. Using HTML and JavaScript, implemented targeted changes to disable visibility for Smarty.cz and TSBohemia.cz, ensuring these shops no longer appear in the user interface or supported shops list. The update was delivered as a single, well-documented commit that clearly outlined the rationale and technical approach. This adjustment improved data accuracy for operators and end users, reduced maintenance overhead, and ensured the extension’s front end accurately reflected the actual monitoring coverage.
