Normcap

- Fix quotes in detected text can result in wrong detection.
([446](https://github.com/dynobo/normcap/issues/446))
- Update AppImage base image from Ubuntu 18.04 (deprected) to 20.04.

- Enlarge settings button a bit to make it easier to spot.
([254](https://github.com/dynobo/normcap/issues/254))
- Prevent running multiple instances and start capture in original instance instead.
([306](https://github.com/dynobo/normcap/issues/306))
- Fix unintended re-capture if tray icon is disabled.
([254](https://github.com/dynobo/normcap/issues/254))
- Fix occasional crashes after use of Language Manager.
- Add experimental `--cli-mode` switch to print NormCap's detection to STDOUT and exit
immediately. This is useful if you want to use the detected text as input for other
programs or commands. E.g.:
sh
normcap --cli-mode | xargs -I {} firefox "http://duckduckgo.com/?q={}"`

- All: Remove support for Tesseract \< 5.0.
- All: Faster startup if "Check for updates" is enabled.
- All: Refactor icon handling. Fixes a bug in the AUR package.
([353](https://github.com/dynobo/normcap/issues/353))
- All: Fix crash if tesseract data for English is missing.
([353](https://github.com/dynobo/normcap/issues/353))
- Linux: Fix FlatPak crashes due to missing permissions
([320](https://github.com/dynobo/normcap/issues/320)).
- Prebuilt packages: Add UI for downloading additional languages.
- Prebuilt packages: Remove all default languages except English to reduce size.
- Prebuilt packages (Windows): Switch to different tesseract binaries, which should work
more reliable across systems. Unfortunately, it also enlarges the file size a lot.
Would be great to [get your feedback](https://github.com/dynobo/normcap/discussions)
on this! ([254](https://github.com/dynobo/normcap/issues/254))

- All: Add possibility to capture by left-clicking (or double-clicking) the tray icon.
This also improves a bit the situation regarding

[311](https://github.com/dynobo/normcap/issues/311).
- Windows: Improve the msi-installer by doing a clean uninstallation that removes also
log-folder and tessdata folder.

- All: Add `--version` command line flag to easily print NormCap version.

printed on screen again. (No need for checking the log file anymore.)
- Linux: Fix FlatPak crashing when gtk3-nocsd is enabled, e.g. in Unity DE
([190](https://github.com/dynobo/normcap/issues/190)).
- Linux: Fix full screen view in Unity DE
([190](https://github.com/dynobo/normcap/issues/190)).

- All: Reduce interval for (optional) update check to 7 days instead on every run to
saves startup-time.
- macOS: Check for required screen recording permissions and warn if missing.
