New Thunderbird add-on: Easy Table Editor by Cardella — feedback welcome

Hello Thunderbird community, I have released Easy Table Editor by Cardella, a free and open-source extension created to make HTML table editing easier inside Thunderbird's message composer. The extension adds a table editor directly beside the message formatting controls and includes: • Mouse-drag selection of multiple cells • Simultaneous formatting of selected cells • Column and row resizing with the mouse • Row and column insertion or removal • Cell merging and splitting • Header-cell conversion • Text, background, border and alignment controls • Clean, modern table templates • The ability to save the current table as a reusable model • Interface localization in ten languages The extension works locally. It does not use analytics, tracking, external servers or remote resources. Saved table models remain in Thunderbird's local storage. Thunderbird Add-ons page: https://addons.thunderbird.net/thunderbird/addon/easy-table-editor-by-cardella/ Compatibility: Thunderbird 151 or newer. This is a personal and independent project. I would appreciate feedback from the community, especially about usability, compatibility and features that would make HTML table editing better. Thank you! Henrique Cardella
