Maggie – have some neat stuff in the oven for Macros. Think you'll be pleased.
On platforms –
TextBlade is a cross-platform device, and its onboard MultiMap capabilities work anywhere you can type.
I think your question is aimed at the companion app, which lets you setup your mappings, and offers enhanced UI. As we port our iOS app to new platforms, the goal is a consistent user experience.
Feature parity is important – and there's good news there. iOS, Android, Mac, and PC all have sufficient technical foundation to support our MultiMap design. Both iOS (since 8.0) and Android (for many years now) support keyboard extensions. Mac and PC allow similar low-level access.
As a developer – you also know that each feature takes finite time to port. Here's a common choice app developers are faced with (using Android as an example):
A. Release Android features as they are available
B. Release for Android once all features are ported.
We feel it's important to get new capabilities in folks hands as they are available (option A).
As an Android user/developer, interested to get your take.
