[Feature]: [Feature Request] Single-click file preview reuse — VSCode-style preview block #3114
Description
Feature description
Summary
When clicking a file in the Directory Preview block, Wave currently opens a new block each time. It would be great to have a “preview mode” that reuses an existing preview block instead, similar to how VSCode handles single-click file previews.
Desired Behavior
∙ Single-clicking a file in the Directory Preview block opens it in a designated “preview block” (e.g., the adjacent right block)
∙ If a preview block already exists, it gets updated in place rather than spawning a new block
∙ Double-clicking (or some explicit action) “pins” the file, locking the block so it’s no longer replaced on next click
∙ The preview block could be indicated visually (e.g., italic title, like VSCode)
Current Behavior
Every single-click on a file in the Directory block opens a brand new block, which quickly clutters the layout — especially when browsing through multiple markdown files or source files.
Use Case
Browsing a documentation folder or source tree and quickly previewing multiple .md / .txt / source files one by one, without accumulating a pile of open blocks.
Workaround
Manually running wsh setmeta -b file:///path/to/file to update an existing block’s file, which works but is not ergonomic for casual browsing.
Additional Context
This is a common UX pattern in editors (VSCode, Zed, JetBrains IDEs). Given Wave’s block-based layout, a natural implementation might be: the directory block “remembers” a linked preview block ID, and routes single-click opens to that block.
