# SequenceFeatureDetails

Auto-generated @jbrowse/mobx-state-tree API for the current JBrowse release — see [pluggable elements](https://jbrowse.org/jb2/docs/developer_guide/) for concepts. Built into JBrowse core. [View source](https://github.com/GMOD/jbrowse-components/blob/main/packages/core/src/BaseFeatureWidget/SequenceFeatureDetails/model.ts).

User preferences for the sequence readout under a feature's details, seeded
from and written straight back to localStorage. Nothing here is snapshotted
or reads the tree, so an instance is cheap and needs no lifecycle: a holder
that only sometimes shows a panel (e.g. a track's right-click dialog) creates
one when it opens rather than carrying it around.

`BaseFeatureWidget` holds one as `sequenceFeatureDetails`, which is where a
caller changing the readout reaches these actions.

Rows exist only while coordinates are shown — without them the panel wraps to its container — so this is what the labels step by, and the line width of the FASTA exported from that state. |
