2.4.9 * Introduce ability to open new tab specifying its position, by long-press on the "New Tab" button. * Better appearance for the contaienr selector on the "New Tab" button. * Warn before closing multiple tabs a a time. * Better behavior and keyboard operation handling of fake context menu. * Better compatibility with other addons which hide some tabs, like [Conex](https://addons.mozilla.org/firefox/addon/conex/). Now tabs hidden on the top tab bar are also hidden in the sidebar. * Always scroll to the newly opened tab when it is opened as the active tab. * Tabs opened from same pinned tab are grouped, only when there are multiple tabs to be grouped. * Group-tab to bundle tabs opened from same pinned tab inherits the container of the parent pinned tab. * Show descendant tabs as the content of a group tab. Clicking on an item will give focus to the tab. * Don't break group tabs when Tree Style Tab is dynamically updated. * Restore group tabs as-is when they are imported from different profile with session information. * More meaningful label for "temporary group" checkbox of group tabs. * Reduce mismatched tree structure between the internal master process and the visible sidebar contents. * A new [alias to specify tabs via API](https://github.com/piroor/treestyletab/wiki/API-for-other-addons#basics-to-specify-tabs): `senderTab` which is resolved to the owner tab for a content script. * Update `de` locale (by sicherist, thanks!)
