Impossible to save custom themes to library after importing JSON

[DuluozPast]

Hi,
I would like to report an issue regarding the custom keyboard theme management (JSON import/export).
The Issue: When I import a theme by pasting its raw JSON string into the editor, the colors load perfectly on the live preview keyboard. However, it is impossible to actually save this theme to my saved themes library.
The issue is exactly the same if I try the alternative logical route:
Click "New" to create a theme.
Type a "theme name".
Click "Import" and paste the raw JSON string.
The live draft updates correctly with the imported colors, but there is no button or action to confirm and permanently save this draft. As soon as I exit the screen, the theme is lost.
Technical Insight: It looks like importing the raw JSON string successfully updates "keyboard_theme_hardware" (the active customizer state) but doesn't trigger a write or append to "keyboard_theme_saved_themes". This might be because the pasted string only contains the properties inside "theme": {} (missing the wrapping "name" object), or because the "Save" action is missing/unresponsive after importing.
Would it be possible to add a "Save Theme" button in the customizer, or ensure that the New -> Name -> Import workflow properly persists the theme to the library?
Thank you so much for your amazing work on Pastiera!

Theme import semantics have now been made explicit in local commit 483fb290 and verified on a physical Titan 2.

• A normal import validates the theme, persists exactly one library entry, selects it, and activates it.
• Import inside an active New draft replaces only that draft's contents, keeps the draft name, completes the required fields, and refreshes the preview. The active theme does not change until Save and use.
• Cancellation or invalid input does not mutate state, and hardware/software theme state remains independent.

On Nightly 0.86-nightly.20260830.153324, a uniquely named normal import remained in the library across process restart. A distinct New → Import draft retained its chosen name and left the active hardware theme byte-identical until Save and use. A software-target import persisted independently. Export/reimport worked, and a fresh ZIP restore recovered all three synthetic library entries; a restored entry could be selected and was shown as Active.

The commit is still local and unmerged, so I am leaving the issue open until review, merge and release.

Final local follow-up after compatibility review and integrated device verification:

81478444 preserves compatibility with the baseline schema emitted by the original theme-export release 58fdb8e86. The original baseline fields remain mandatory and type-strict; fields introduced later receive their established defaults when absent and remain type-strict when present. Empty objects, missing baseline fields, and wrong types are still rejected.

On the final integrated T2 Nightly 0.86-nightly.20260830.161026 (versionCode 1788106226), a rich ZIP restored into freshly cleared app data with the three synthetic library entries NormalImport287, DistinctDraft287, and SoftwareImport287. All three were visible together in the ordinary Theme library UI; selecting NormalImport287 immediately marked it Active. This required no app or device restart and retained the separately verified hardware/software import semantics from 483fb290. The complete testStableDebugUnitTest suite passes.

These commits are local and unmerged; this issue remains open until review, merge, and release.

Hi Patrick, Thanks a lot for the update and the clear explanation! The new import rules (normal vs. draft) sound perfect. I really appreciate you testing this on a physical Titan 2! I'll wait for the official release and will close the issue once I can update the app. Thanks a lot, have a great day! Le dim. 30 août 2026, 15:45, Patrick Zauner ***@***.***> a écrit :
