Agreed. Moreover, the overhead of importing/exporting data for each step
of a complex analysis puts GRASS algs to a disadvantage for Processing
users.
BTW, I'm unsure about the G7 support in the Browser: could someone check
thoroughly?

Yes, I have been talking about that. Radim did most of the work on the
plugin. If he (or eventually others) are available, a crowdfounding
initiative could be appropriate.

Obrigado for this.

Yes, these are adaptations of the original commands, in order to make
them more usable from QGIS.

Overall, I think these are minor issues. If someone really miss them,
they can ask, and we can add them.

All the best, and thanks again.
