Feature Request: E-ink optimized theme and adjustable font size

[Morglaf]

Description Thanks for this great app, it works perfectly! I'm using it on a large E-ink screen and would like to suggest two improvements for better usability:
E-ink Theme: A basic black & white high-contrast theme (no gradients/shadows) to prevent ghosting and improve clarity.
Font Size: The ability to increase the text size, as it is currently too small on large displays.

Thank you again for your hard work on this project!

Have you tried Settings -> Dictionary View Color Scheme -> Display Scene -> Ink Screen?

[Morglaf]

Thanks for the quick reply! I did try the "Ink Screen" setting, but it still has some issues on my device:

Backgrounds: Several UI elements and backgrounds remain grayish rather than pure white, which causes ghosting.

"Tap Anywhere" Window: This is the main issue. The background is gray and the buttons are almost invisible/unreadable.

Font Size: Even in this mode, the text remains too small for large displays.

Could we have a "Pure Black & White" option (High Contrast) that applies to all pop-ups and buttons, along with a font scaler?

Could you take a screenshot so I can take a look?
As for the font size, there’s not much I can change on my end, but you could try increasing your system font size

Here are the screenshots.

Note on visibility: While these screenshots look clear on a standard LCD/OLED screen, the experience on an E-ink display is quite different. On E-ink, any gray area (like the "Tap Anywhere" window or the background in these images) triggers a lot of ghosting and reduces contrast significantly.

Thanks for taking a look!

Got it, and unfortunately, I can’t fix this right now because my BOOX e-ink reader’s screen broke a few months ago, so I don’t have a device to debug on at the moment. I’ll follow up once I have a reader again in the future.

Thanks for looking into it! Sorry to hear about your BOOX reader's screen. No rush at all, I'll keep an eye on this ticket for future updates whenever you're able to get a new device.
