I agree. Removing the prompt to add an external to the user paths makes sense in the context of [declare -path] searching user paths. Without this step, we're back to the problem of "I installed an external, but I can't load it, help." I know this prompt is loathed by some but it also keeps the amount of "help me" email down in the meantime until 0.49 includes the [declare] update.

1- There's a default change, now it doesn't prompt you no more if you want
to add externals to the path. I get it this is more than intentional and
would like to inquire why. Thinking in the mind set of a newbie and
newcomer, this might be handy to suggest. Advanced users who are annoyed
can edit it in the preferences. Anyway, that's just my two pennies on it.


I have a new consideration about this. Since Pd suggests the creation of a
documents folder, and since declare isn't working for that option yet (and
since miller is holding that fix for 0.49), it makes sense to me to keep
prompting the user to add the folder to the search paths because that's
what will help him best, as you'd actually need to include it in the search
path if you were were to use Pd default's suggestions. Advanced users can
still edit this for more complicated and different kind of setting.
