Why is there still no nested search 🔍 capability in VSCode?
"Files to include" should allow to reuse the last search results.
This would be such a low hanging fruit and would make the search 100x more powerful.

In the age of ChatGPT and all the other AI innovations, I don’t get why Alexa & Siri still suck. 🤯
It’s like talking to a very old person with bad hearing.
You ask for a simple task and you get an unrelated response.
Or better yet, my Alexa pretends to be completely deaf sometimes.
Frustrating 😠

Coming from iTerm2, I really like @warp.dev 💜
Workflows with dynamic params are just magical 🪄 and make my life so much easier.
Would love to see those features coming soon:
1. Define your own keybindings for switching to next/previous
tab
2. Merging tabs into split view
Keep going 🚀

There are people that are patiently and with a lot of effort explaining the problem they want solved talking to an LLM.
But some of those very patient people are NOT so patient when they interact with humans.
I wonder why? 🤯

Why is there no family plan for ChatGPT or Claude? 🤔
Team plans are for businesses, but what if you would like to share with your family?
Like Spotify or Netflix.

Back in the day, when I was going to school, I used flashcards sometimes. Creating them was tedious. 🥱
Today I helped my kid:
- scanned 50 handwritten pages
- uploaded to ChatGPT
- asked for generating 200 Q&As
- exported XLS with 2 column
- printed, folded, cut
- done
What a time to live in 😅

Did someone think of an MCP server for Amazon shopping already? 🤔
I could imagine such a better shopping experience by just handing over the tasks of finding and researching products and their features, comparing reviews, detecting fake reviews, checking delivery costs, and more
Do I dream to big?

When I have to write a piece of content (e.g. presentation, documentation, …), I always worry about not having enough topics to talk about. 😧
Then I get started. A bit here, a bit there, usually very chaotic.
By the end, I have too much content and need to cut down. 😅
Every single time. Weird 😐
