Project: QGIS
Version: 3.30
The topology checker plugin has been improved to provide functionality for better management of rules, as well as filtering on large error sets. Additional enhancements bring the UX more in line with later QGIS releases and allow productivity enhancement such as bulk deletions and rule disablement.
The topology checker rules dialog now features check boxes which are attached to individual rules, which allow for enabling/ disabling rules when running validity checks without having to remove them. This avoids scenarios when users don't want to lose rules but are only interested in validating a subset.
The topology checker panel also has a a new combo box below its toolbar to allow for quick filtering of errors to allow users to focus on a specific error type, although it will continue to display all error types by default.
