Feature Requests, date range presets, all tracker preset, ability to auto scrape on a schedule

[yroyathon]

Here are a few changes/additions that would make me stop doing my tracker tracking manually and use Dasharr exclusively.

Date Range dropdown presets: YTD, 1 Year, 3 Years, 5 Years, Max
Tracker dropdown preset: All Trackers (or All Enabled Trackers?), and select specific/multiple trackers (for comparing just a few trackers, can be helpful for trackers with similar data size ie very large or very small)

These two UI changes would present me with a single chart containing many lines/curves where I could easily confirm all is well. I could easily spot an outlier that dropped or was missing in the last month. All without having to iterate N times through the tracker dropdown.

Another change that would be very handy is a scheduled scrape option, with the UI portion being a numeric dropdown plus a Unit dropdown(Week/Month). Personally, I'd set it to "1" and "Month" to do an automatic scrape on all enabled trackers each month. This way, no matter when I logged into Dasharr to check on things the data would still be collected. When I did login, the view of say All Trackers and data Ratio and Date Range YTD would show me view of my trackers ratio over time. All without requiring me to login and click the scrape button each schedule period (very convenient).

Very nice work on the app revamp, I can see this getting very popular.

Interesting suggestions, I'll look into them at some point.

Regarding scraping, as it is explained in the readme, it is already done automatically every 6h

Re automatic scrape, superb.
