Guided by Leo’s Interaction Design Philosophy, I decided to make a subtraction:
- Remove the toolbar from table panel.
- Remove New Table from the table right-click context menu.

Removed the DDL preview toolbar. Actions moved to the context menu.
Why:
1. A cleaner, calmer UI
2. Non-frequent actions should stay out of sight
3. One action, one clear entry point
When the work starts to feel like subtraction,I know I’m getting close.

While everyone is busy building thin GPT wrappers, I’m engineering the professional workstation for the next decade of AI data.
I’m feeling a real sense of urgency for #DataCollie.
The future is clearly in Vector DBs, visualizing similarity and vector search is the must-have for AI infrastructure. Yet, here I am, stuck on MySQL.
It’s a race against time, but I know where I need to be. Get it done.

Yesterday, i added a new tab view that lets you browse foreign key constraints at the schema level.
Hopefully, it makes the db structure esaier to understand and reduces mental overhead.

#DataCollie One Step a Day
It’s Saturday. I woke up earlier than on a workday and felt that “being woken up by a dream” again.
In just one morning, I implemented:
1. Editable Column Name field in the table.
2. An Add button that inserts a new Index Column.

Got home late tonight, didn’t code, just reviewed what I’ve built so far. Looking back, I’ve done something meaningful past year. the best thing about being a developer? You can lose yourself in your own product, no midlife crisis, no emptiness, no loneliness. #DataCollie

For vector databases, GUI client tools are not just productivity aids. It don't just need visualization; the depth and approach of their visualization directly determine how efficiently users can leverage this powerful AI-native infrastructure.

For vector databases, GUI client tools are not just productivity aids. It don't just need visualization; the depth and approach of their visualization directly determine how efficiently users can leverage this powerful AI-native infrastructure.
Vector DB clients differ from traditional RDB ones — they run similarity searches and interpret scores, not exact matches. It’s about semantic exploration, not logic filters. The next wave of DB tools starts with native vector support. #DataCollie #buildinpublic
