Allow plugins for task lookup
The task lookup integration is great if you have full SQL access to the source of the task list, but in some environments you have an API without SQL access (like in a Microsoft Project Server environment). It would be nice to be able to write a plugin for task lookup integration rather than requiring SQL.
The SQL integration could then also be written as a plugin that ships with TimeSnapper by default. Task lookup integration would be done by selecting the desired plugin and configuring that plugin.
