Release v0.4

[✨ Feature] Now macOS Compatible!
Twilio Blaster is no longer limited to Windows—it now runs on macOS too!

[✨ Feature] Scheduled Messages
You can now finally schedule your messages (SMS, MMS, WhatsApp) to a specific date and time—and cancel any scheduled messages if needed. More info: https://pythonandvba.com/go/twilio-blaster-schedule-message-docs

[✨ Feature] WhatsApp Messaging Support
You can now also send WhatsApp messages directly from Twilio Blaster. Set up your WhatsApp account in Twilio and start sending WhatsApp messages (incl. images). More info: https://pythonandvba.com/go/twilio-blaster-whatsapp-documentation

[✨ Feature] Real-Time Progress & Cancel Option
A progress bar now shows you how many messages have been sent, and you can cancel the sending process at any time with a new cancel button.

[✨ Feature] Message Status & Pricing
You can now check the status of your messages after sending them. See whether your messages have been delivered and view the price you’re paying per message.

[✨ Feature] New License Manager & Update Checker
You can now view your license status and renew it directly from the tool. Plus, a new “Check for Updates” button makes it easy to confirm you’re using the latest version.

[✨ Feature] Table-Based Message Sender
The message sender is now organized as an Excel table. This means you can extend, move, or adjust your messages easily.

[🌱 Improvement] Fallback Placeholder Syntax
You can now specify a fallback value right in the placeholder using a pipe symbol. For example, if you write: "Hi {{customer_name|there}}," and no value is defined for customer_name, Twilio Blaster will automatically use “there” as the fallback. This ensures that your messages always have a sensible default.

[🌱 Improvement] Smoother Delay Handling
Long delay settings no longer freeze Excel. Addtionally, delays are now capped at 24 hours (86,400 seconds) to prevent crashes.

[🌱 Improvement] Pre-Send Data Validation
Before sending, the tool now checks that phone numbers look correct and verifies that your Twilio settings (account SID and auth token) are entered properly. This helps prevent wasted attempts.

[🌱 Improvement] Enhanced Paste Formatting
When you copy and paste numbers (for example, from the number converter or another spreadsheet), the tool preserves the original formatting. (You can disable this feature in the settings if you prefer.)

[🌱 Improvement] Customizable Notifications
Success and notification messages can now be turned off in the settings for a quieter user experience.

[🌱 Improvement] Further Enhancements
I’ve made a range of backend improvements to make the tool more robust and reliable.

[🐛 Bug Fix] Placeholder Crash Prevention
Previously, if a placeholder value contained a formula error, the tool would crash. Now, errors are flagged in the check column and are safely converted to empty strings, so the process continues smoothly.
