Creating a scene for several device is just a pain, the activity layout should scale according the screen size of target device, it shouldn't use any absolute layout or fixed aspect ratio.

Please allow separate Tasks to turn logging on and off for that particular Task. This setting should also carry over to all tasks called by the Perform Task action.

Another idea would be an option to turn off logging in the Perform Task action.

Tasker should have its own "No-SQL" like database to store and retrieve complex data rather than  just variables. 

This will also allow variable backup and any data can be queried remotely without having to setup a profile for each of the stuff

Being able to create apps within Tasker is probably its neatest feature, but there's one rather annoying caveat: there's no option to export with additional files!

You have to use convoluted workarounds such as this: Reddit

There's also an app that helps you do it but it has file size limitations. Play Store
