The default issue search in MantisBT changes the global state, so one cannot keep 2 tabs up to date with different issue filters. This plugin provides a simplified interface to search issues, with no side effect.
Unfortunately, this is not possible without patching MantisBT. The official REST API can only fetch issues through saved filters. This patch enables on the fly filters in the API.
The plugin texts are French and not localized.
Install the code in Mantis, and build the JavaScript code (no pre-built package is available).
git clone ... plugins/Search
cd plugins/Search
yarn install
yarn build
Then configure Mantis through its web interface to enable the plugin.
