To import plugins or load themes:
+ import plugins/<plugin>
+ import plugins/{dpaste,cask} themes/bobthefish
Note: Plugins/Themes can be in either `custom/plugins`, `custom/themes` or `$fish_path/plugins/`, `$fish_path/themes/`.
+ All `.load` files inside custom are sourced as usual.
+ Only set plugins set in `$fish_plugins` as imported. Works whether they are in `$fish_path` or `$fish_custom` as expected. The same for plugins.
+ `$fish_function_path` is not polluted.
