Gifcurry does not optimize using Gifsicle. It employs the optimizations afforded by ImageMagick. In most cases the Gifsicle file size reduction is only minimal (even with the "-O3" flag).
Gifcurry controls the window size to maintain an accurate preview of the video (no added bars, wrong aspect ratio, etc.). This becomes important when cropping. If desired, I can add a preview size setting.
A preview of the text would be nice. This will be a future feature.
The upload buttons are shortcuts. This avoids having to maintain and distribute/reveal API keys. It also avoids having to keep the integration accounts in good standing.
The quality setting can reduce the final file size. Still, using your benchmark, I tweaked the optimization and pushed an update to the AUR.

Still, if desired, I could add this extra step.
