It way longer than expected but finally here we are: https://download.geany.org/snapshots/geany-1.39pr973%2B1195_setup.exe https://download.geany.org/snapshots/geany-plugins-1.39pr973%2B1195_setup.ex...
@zhaolinlau would you mind installing these two (they will replace your previous Geany installation) and give it a try? As above, the plugins installer contains the TreeBrowser fixes for #973 and #1195.
One more note: the installers contain the current GIT master code (except for the mentioned PRs) and so the new version will move some settings of your Geany configuration file into a new `session.conf`. You should not notice this but in case you want to switch back to the old version, everything stored in the `session.conf` will be ignored by the old version. Maybe just make a backup of your current configuration (should be in `C:\Users<username>\AppData\Roaming\geany`).
