I found a funny bug (or bad behaviour at least)
The value of BTT_PRESET_PATH is sometimes set to an unexpected value.
This is with 3.328

To reproduce this,

  1. set your preset to not default and generate a trigger (I associate it to the opening of a html page)
    this html opened as expected -> correct BTT_PRESET_PATH
  2. change your preset to default
  3. edit the previous trigger and add a second web view

This second webview does not open. The reason is that the BTT_PRESET_PATH for this second action is set to the default preset and not the one associated to the trigger...

The workaround is simple obviously.

Weird I can't seem to reproduce this. Does it work after a restart?
Are you sure the triggers are in different presets?
