`|>` could possibly be used instead of `>`, similarly as it is used in 'ggplender'. But in 'ggblender' `|>` works across multiple layers, not just a pair of layers.

The best bet for adding support for fitting various distributions individually seems to be to use `MASS::fitdstr()` as it is safe to depend on 'MASS' as is already being imported.

`stat_distrmix_line()` and `stat_distrmix_line()` support also fitting a single distribution. Currently, the Normal. - [ ] What other distributions can be supported? - lognormal, possibly - Gamma, possibly

'gridExtra' has not been updated for quite some time. Thus, this can be implemented as in the example above. The reason to use `ggplot2::alpha()` instead of just passing `alpha` to...

- [x] Update all ttheme constructors adding formal parameters `base.alpha`, `rules.alpha` and `canvas.alpha` to make it easier for users to create semitransparent table themes. - [x] Update `geom_table()` and `geom_table_npc()`...

Getting the logic for defaulting to ttheme but supporting both colour, fill, and alpha in a way the mapped or constant alpha aesthetic is applied to the theme defaults when...
