Show HN: Safari extension that adds Chrome-style bookmark star to the toolbar
Bookmarks Star for Safari will put a star icon into your Safari browser's toolbar. The icon will switch to a color of your choosing when you're visiting a page that is already in your Safari bookmarks (so no more creating accidental duplicate bookmarks). Also, you can see the exact folder(s) where that page is bookmarked when you click on the star icon (super handy if you have lots of folders). Additionally, I added a bookmark analysis feature, where you can create a report of all your duplicate bookmarks (so you can clean up duplicates).
Bakckground: I am kind of a semi-retired veteran (worked at Amazon and Google before) and I have been using Mac systems for more than 20 years, and used all kinds of internet browsers, but mostly Chrome until last year. Around 6 months ago I switched to Safari and the difference in terms of performance and resource management is very noticeable for my use case. Safari easily manages 50-100 tabs for me without any hiccups.
I am a heavy bookmark user (~4000) and one thing I was missing from Chrome was the "star" icon you see in the address bar that instantly shows if the page you're visiting is in your bookmarks.
I tried using third party bookmark managers but I thought they "added" to my workflow instead of making it easier (not extremely simple to use & creating separate databases for bookmarks etc.).
I also wanted a privacy-oriented solution, where my bookmarks were not stored somewhere in a 3rd party cloud, and I wanted to have an instant visual feedback like I had in Chrome (can't remember how many duplicate bookmarks I've created in Safari due to being lazy).
The extension only reads the URL of the active tab to check if it is bookmarked and does not read/track/store any website content. It also does not send/receive any data to/from any servers outside the computer. It does not use any trackers or analytics.
The app is live on the Mac OS App Store with a one-time fee of 3.99 USD (no subscriptions or in-app purchases. Buy once and use forever).
Your feedback is appreciated! if you have questions about anything, I’m happy to answer.
I hope you'll like it!

Ask HN: Trump's return affecting freelance work?
I'm a Laravel/Vue freelancer in Germany with 10+ YOE. After 3 years of steady well-paid work, I've seen a significant slowdown since January when Trump returned to office.
Projects postponed, leads going cold, follow-ups unanswered. One American client specifically mentioned "caution around tariff discussions in the US" when canceling my project.
Are you experiencing this as a freelancer? If you hire freelancers, have you pulled back recently? Particularly interested in perspectives from different countries.

Ask HN: Why so many companies reducing middle management recently?
I understand why you’d want to reduce middle management and eliminate layers of hierarchy
But why would companies all do it at the same time like it’s a trend?
