v9.115. 4. 2026

Folder kebab menu on the dashboard now shows a standard dropdown (Rename / Delete) instead of a numeric prompt.
Code card actions on the dashboard are now visible buttons side by side (Edit, Rename, Move, Delete) instead of a hidden kebab menu. Folder chips show rename/delete icons on hover.

v9.015. 4. 2026
New dedicated "My Codes" page (/my-codes/) with sidebar navigation, folder management, QR thumbnails, search, type filter, sorting, bulk selection, and bulk actions (delete, move to folder).

Saved QR code preview thumbnails are generated client-side with in-memory cache using a pure payload builder (no DOM dependency).

v8.010. 4. 2026
Added new eye style "Soft square" for outer frame and inner dot, matching the rounded square look from the provided reference.
Payment fields now include browser autofill metadata (name/autocomplete), so Chrome better offers to save and reuse IBAN/account.
The "Split IBAN to CZ account" action now appears only in IBAN mode and immediately shows clear feedback for invalid CZ IBAN.
SPD conversion buttons now perform a visible action: switch mode and immediately show converted fields or clear guidance for invalid CZ IBAN.
Payment amount fields now enforce strict format (positive number, max 2 decimal places) including comma-to-dot normalization.
Recipient name and note in SEPA now validate EPC characters and display a live remaining character counter.
SPD conversion is now bidirectional: you can calculate IBAN from a Czech account and split a valid CZ IBAN back into prefix/account number/bank code.
Payment forms now continuously validate IBAN and BIC/SWIFT for SPD and SEPA fields including inline error highlighting.
Payment QR generation is blocked when SPD/SEPA data is missing or invalid, and a centered warning with instructions is shown in the preview.
In SPD account number mode, the Prefix / Account number / Bank code fields are stacked vertically, so the Account number field no longer gets clipped in narrow panels.
Date and time fields on the Event card have the same design as other inputs, and Start/End are stacked vertically for better readability in narrow panels.
The birthday field in vCard now matches the design of other input fields.
The Galaxy template was adjusted for higher scan reliability while preserving the visual style.
Score scale labels are aligned to actual boundaries (0/60/75/90/100), so the needle position visually matches the displayed score.
