Extended search functions on song list screen (develop)
On the song list screen you can activate the search function by pressing F3 or CTRL+F, even in older Vocaluxe versions. In this commit I added special keywords for this search function to allow searching just for the artist or other items, like language or genre, which can't be searched in older Vocaluxe versions. (changed file CSongFilter.cs) Use following keywords to search for a special item: a: = artists t: = title g: = genre y: = year, you can also do y:1980-1989 to find songs from the 80s l: = language c: = creator e: = edition al: = album fi: = file name fo: = folder name **Examples:** a:abba y:1980-1989 y:1999 g:rock l:german **Additional notes:** - If using this keywords, the maximum search results are limited to 200 songs. - Changed the behavior if searching without keywords: Only title and artists will be searched, removed folder and file names.
