Simple Bluetooth Printer

Save & Open — text/image/receipt/invoice documents saved and browsable from one "My Documents" list, accessible via Actions menu, with quick-save shortcuts throughout. Receipt Templates gallery — built-in Restaurant/Retail/Minimal receipt and Standard/Minimal invoice designs with live previews. "Edit as Text" moves a composed receipt/invoice into the main editor for free-form editing before printing. Print from Web — capture any webpage as an image and print it. Print Document — render and print multi-page PDFs, with a fix so a dropped printer connection mid-job now shows an error instead of silently stalling after 2 pages. Rich text formatting — Bold/Extra Bold/Underline toolbar on the main editor (works on selected text), plus a formatted preview screen. The broken alignment button was removed and replaced with a direct placeholder-insert shortcut. Placeholder picker — now lists all ~30 built-in placeholders (dates, invoice/serial numbers, calculations like {{SUM()}}/{{TAX()}}, separators, print commands), grouped by category, not just your own custom ones. Localization — Bahasa Indonesia, Portuguese (Brazil), Hindi, Bengali, Malay, Vietnamese, plus an in-app language switcher in Settings independent of the device's system language. Also fixed: slow/frozen image-document opening (now async with a loading spinner, and images are downscaled at save time for speed).
