Great, thanks. Now we need to be able to post directly from Npub.pro.
Big update on Npub.pro!
We've added manual content management for you. Basically, not only can you import content onto your site with hashtags, you can also manually select which posts to publish.
Let me use https://whynostr.org as an example. It's a new site where auto-import by hashtags is completely turned off, and I manually add new posts to it.
On the site Dashboard we have "Posts" button now:

The first thing you'll see there is all posts already published on the site:

You can filter through published stuff:

And you can tab "Add post" to find and publish another piece. The first thing you'll see there are "Post ideas" - posts by same authors and similar hashtags like ones you already have.

Post ideas are very rough now, so you'll probably want to tap "Search posts" to find something good on Nostr:

I'm looking for the most recent Article by nostr:nprofile1qyghwumn8ghj7mn0wd68ytnhd9hx2tcpzamhxue69uhhyetvv9ujumn0wd68ytnzv9hxgtcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsz9nhwden5te0dehhxarjv4kxjar9wvhx7un89uqsuamnwvaz7tmwdaejumr0dshszxmhwden5te0wfjkccte9ehx7um5wfcxcetzwvhxxmmd9uq3xamnwvaz7tmhda6zuat50phjummwv5hszxnhwden5te0wpuhyctdd9jzuenfv96x5ctx9e3k7mf0qy0hwumn8ghj7mn0wd68yttjv4kxz7fwv3jhyettwfhhxuewd4jj7qpq8ams6ewn5aj2n3wt2qawzglx9mr4nzksxhvrdc4gzrecw7n5tvjqzxvm96 , I find it by name and can tab "Add" to publish it on the site:

That's roughly how it works. You can go to Settings to completely turn off auto-submission by hashtags, or you can simply augment auto-submitted posts with occasional manual submissions.

This has been long in the making and lays the foundation for huge number of new features. Each manual submission is a separate nostr event, which means we can now create various automations and bots to find and submit content to your site - something not possible with hashtag-focused approach.
More updates are coming soon. Meanwhile, please try this and let us know what must be improved!
Discussion
I would hope to avoid that, leaving it for other clients. Does none of Habla, Highlighter or Yakihonne work for you?
Btw each contributor on your site can log into npub.pro and can manually add posts to your site. This kind of clashes with auto-submit by hashtags, so maybe it's best to remove the contributors and manually add their posts.
