I'm using an ageing Nexus 6 with Android 7.1.1. The problem I have with most multi-featured keyboards is that they don't show and hide timely with my pace of app usage. So, with animations disabled, when I swiftly switch to an app and the keyboard was opened in last used app, it would not hide out with a breeze. Often I find a gap of one or more seconds which I find irritating and unproductive.
Using Back key doesn't really work in such cases. So with this problem in mind, I looked for lightweight keyboards and came across Hackers Keyboard. So far so good. It does irritate me and lacks some really useful functions, but what's disappointing is the size of its space bar. It is too narrow and I cannot increase its width.
Until now I used Gboard (Google Keyboard) which had enough width to accomodate my typing style. I also tried some other keyboards such as TouchPal, SwitKey, Google Indic Keyboard and while they provided sufficient Space bar width, they all suffered with the same problem of untimely display of keyboard when switching apps on my device.
So, is there a keyboard which matches my needs, both being lightweight and comes with a resizable space bar?
I'm perfectly fine with any suggestion (gratis or otherwise) within aforesaid constraints as long as the keyboard can be resized.
For reference: Hackers Keyboard and Gboard respectively.
