## Summary
|
|
|
|
Message rendering as a `List` of pre-wrapped rows with an explicit 1-column scrollbar, a write box whose height grows from its visual row count, and a notable reverted experiment: right-aligned outgoing bubbles were tried and abandoned as ugly. The rejection is as valuable as the patterns.
|
|
|
|
## Key findings
|
|
|
|
- Messages render as a `List` of pre-wrapped rows with an explicit 1-column scrollbar.
|
|
- The write box height is dynamic, derived from its visual row count (capped by config).
|
|
- Right-aligned outgoing message bubbles were implemented and then reverted as ugly; all messages stay left-aligned rows.
|
|
|
|
## Pros / strengths
|
|
|
|
- Pre-wrapped rows plus an explicit scrollbar are simple and portable — no layout-engine support needed.
|
|
- The documented bubble rejection settles a design argument with real-shipped-client evidence instead of taste.
|
|
|
|
## Cons / limitations / caveats
|
|
|
|
- No markdown, streaming, or tool-call rendering in the inspected evidence; the widget covers plain message rows only.
|
|
|
|
## Relevance to tai
|
|
|
|
- Decisive for the messaging-layout conclusion: tai renders left-aligned wrapped rows with sender grouping, not bubbles, and grows its input from visual rows — both directly from this source.
