I'm not a trained designer, but just looking at the screenshot in the readme:
- The orange and the purple are both very bold, non-standard colors. Using one or the other makes sense as a way to draw attention to important things and give the tool personality, but having both together is a little grating. Perhaps the orange should be replaced by red? This would also be idiomatic in terms of what those buttons seem to be doing.
- I think there are too many different shades of grey; the title bar, the main background, the white sections, and the category headers are all different shades. Also, something feels off about the color on the category headers. I think part of it is you have white text on a medium-gray background, which isn't quite enough contrast, but part of it may also just be the fact that those headers are darker than the "main" background color. On the other hand, it could look good to just use the title bar color on the category headers. Hard to say without trying it out.
- The transactions table could use a proper border all the way around (it's visibly absent on the top and sides).
- A clearer division could be made (a border line or just a bigger gap) between the "categories" and "transaction" sections, because it's not immediately clear what "delete all" will be deleting.
- The "delete all" and "add new" buttons aren't aligned with the left and right bounds of their section; also, there's no reason for them to be spread out so far. They could gravitate to the right, for example.
- Bolding the field labels below the word "transactions" would make it slightly clearer what purpose they serve, and vertical-aligning them with their respective fields would be slightly more pleasing.
- Making the gap beneath each "sub-category +" larger than the gap above it would help connect it to the table it pertains to.
Unfortunately I think changing the category header text to black with the same background may have made that part worse; I'd probably make the text white again and the background the same color as the bar at the very top
Yea, no offense intended with this, my first thought looking at the project is that it's a scam or malware. I would have to personally read through the source code to feel comfortable using this. The main thing is none of the text is vertically centered and everything is lowercased. Maybe I'm just paranoid about financial software.
Ah, thanks - I thought I improved it from earlier versions. What in specific do you not like about it? Specific things can help development further.
